-- “I am absolutely devastated at this tragic and unexpected news. For Michael to be taken away from us so suddenly at such a young age, I just don’t have the words. Divinity brought our souls together on The Wiz and allowed us to do what we were able to throughout the 80’s. To this day, the music we created together on Off The Wall, Thriller and Bad is played in every corner of the world and the reason for that is because he had it all…talent, grace, professionalism and dedication.He was the consummate entertainer and his contributions and legacy will be felt upon the world forever. I’ve lost my little brother today, and part of my soul has gone with him.”
--Quincy Jones

-- "Rarely has the world received a gift with the magnitude of artistry, talent, and vision as Michael Jackson.

We wish his children and entire family our deepest condolences."
--Martin Bandier, chairman & CEO of Sony/ATV Music Publishing

--Britney Spears

He had a troubled and complicated life and despite his gifts, remains a tragic figure. My wife Deborah and I will always have great affection for him.”
--John Landis

-- "The entire Apollo family is saddened to learn of Michael Jackson’s untimely passing. Michael first performed at the Apollo in 1969 with his brothers when he was only nine years old, winning Amateur Night, and catapulting their career as the Jackson 5. We will always remember Michael in our hearts as a true Apollo legend, known for his professionalism and grace. Our sympathy goes out to his entire family. He will be deeply missed."
--Jonelle Procope, president/CEO, the Apollo Theater Foundation, Inc.

--Lisa Marie Presley, former wife of Michael Jackson and daughter of Elvis Presley

--Dick Clark, host of the old "American Bandstand."

-- "The death of Michael Jackson is not just a huge and tragic loss but it sadly heralds the end of an era. Michael changed music-making and the music industry. His videos raised the bar to new standards and his tours around the world took music theatre to unprecedented levels of artistic and technical excellence. He leaves behind a body of work that will be listened to by generations to come. It was a personal privilege to work with him and I cherish many happy memories we had together. My thoughts lie with his family and particularly his children."
--Jonathan Morrish, former Sony Music executive from 1976 to 2003 and U.K. spokeman for Jackson, current director of PR and Corporate Communications for PPL

-- "The news of Michael Jackson's death is a shock. The fact that he was planning massive concerts in London and elsewhere suggested that he was on the way back, but this was not to be. His concerts sold vast amounts of tickets and he was a hugely important artist, but his fragile psyche found that success hard to handle. It's very sad."
--Roberto De Luca, organized Jackson's concert at Milan's San Siro stadium show in June 1997, as head of Milano Concerti, later acquired by Live Nation which he now heads in Italy

-- "Michael Jackson is one of the greatest musicians of our time and I am shocked at his untimely death. For most of our generation, he was an icon who made uncompromising music. He pushed the milestone of pop music to unbelievable levels. I am yet to find an artist with that energy, perfection and vision. I had a chance to meet him personally after the Oscars in Los Angeles. He said that he loved India and the Indian people. He said he heard good things about me and he was praising the chord progression of Jai Ho's chorus [from 'Slumdog Millionaire']. He was bursting with energy and told me that every dance move he did came from his soul. He was concerned about developmental issues such as global warming and about wars and its damages to the human community. He asked me to compose a unity anthem on the likes of 'We Are The World' for him. I nodded in awe! He introduced me to his three lovely bright Kids. After hearing the shocking news I wished it was another rumor which would fade away soon. It took me time to believe that he is no more. Life is short! Artists and their art live for ever. Jai Ho, MJ! We love you for your music, regardless of all the controversies!"

-- "I am so grateful I could work with the king of the music industry."
--will.i.am reportedly told a Paris audience during a DJ set when news broke

-- "We all have something of Michael Jackson in us, this is fascinating. He embodied the perpetual teenager, which is a revolution of the past 20 or 30 years. But unfortunately, you can't go against nature. The death of Michael Jackson has an incredible symbolic power."
--Frédéric Mitterrand, newly appointed French minister of Culture

-- "I just can't admit he is with us no more. I have an autograph he once gave me on one of his hats which I always valued so much - it now takes another dimension. This is a great loss, but Michael Jackson will live forever."
--Céline Dion

-- "Michael's death is a tremendous loss around the world. He was an incredible entertainer, a musical genius who moved generations of fans. He crossed cultural and geographical boundaries, elevated music videos to an art form and was inextricably tied to MTV. His music will live on and continue to entertain us forever."
--MTV statement

-- "Michael Jackson was my generation's most iconic cultural hero. Courageous, unique and incredibly talented. He'll be missed greatly."
--Russell Simmons, hip-hop entrepreneur and founder of Def-Jam Records.

-- “Michael Jackson was clearly one of the greatest entertainers of our era. His influence dominated and defined our culture not only in music, but in fashion, dance, film and so much more. Often overlooked are his spectacular skills as a songwriter, composing both music and lyrics for his immense body of work. In an era in which most songs are composed by teams, Michael was the sole composer of dozens of songs that endeared him to audiences around the world. A BMI songwriter since 1976, his BMI catalog contains more than 150 songs, more than 20 reaching multi-million performance status on American radio and television.”
--Del Bryant, president/CEO, Broadcast Music, Inc. (BMI)

-- “Michael Jackson will live forever through the thing that he put all of his life energy into: his music. I will do my part to keep the melody alive, to keep the energy forever changing form, but never ever dying!! Long live Michael Jackson.”

-- "I met Michael Jackson at the age of eight -- when his father and my new friend, Joe Jackson, first began to bring the Jackson 5 to Chicago, from their home in Gary, Indiana, for concert appearances. As the word of the Jackson 5’s devastating abilities as concert artists had already begun to spread like an out-of-control forest fire -- to the, laser-like, attention of all Chicago area, R&B Music Stars! The prevailing thought process, among local, R&B stars, with respect to this very young group of entertainers known as the Jackson 5, had become: If Michael Jackson & his brothers were booked on an, upcoming, Chicagoland show -- leave it alone! Don’t book it -- Don’t go on that show and get, completely blown away by young Michael and the Jackson 5!! Michael Jackson’s, personal, crescendo of amazing power, as an entertainer -- was clear and unmistakable; and has never slowed to this very day! His passing will be grieved far beyond that of any other singer, composer, producer, dancer and choreographer, in the history of
the world. Indeed, in my very firmest, personal, belief there will never, ever, be another Michael Jackson!"
--Don Cornelius, creator of Soul Train

-- "To the best of my knowledge Michael played his last proper live date as part of the HiStory tour in Durban, at King's Park Rugby Stadium on Oct. 15 1997. He had a very special connection with this country. I think what he liked most about being here was the space that people gave him in spite of his huge South African fanbase. He was very giving, getting out the car when he arrived at Cape Town airport and greeting people. I think there are many ordinary South Africans who have photographs with Michael because of how at ease he seemed to feel here and how prepared he was to mingle with his fans."
--Duncan Gibbon, strategic marketing director, Sony Music Entertainment Africa

-- "I am deeply shocked about the death of Michael Jackson. He was an artist who was shining above all the others and his music was epoch-making. As marketing manager I was responsible for the marketing of the albums 'Dangerous' and "HiStory" in Germany. He was so intense [as an artist] that even today I get goose pimples. My personal recollection is of our playing Sony PlayStation in the middle of the night at the Hyatt Regency Hotel in Cologne. I never had a chance against Michael and lost with decency against one of the greatest."
--Mike Heisel, former product manager for Michael Jackson at CBS in Frankfurt and current chairman of the association for music-producers, Mpag

-- "For all of us he was, in his best years, a money-making machine. So many people profited from his genius and earned a lot of money. He was a Peter Pan in the body of a great musician."
--Jochen Leuschner, former CEO of CBS in Frankfurt and current music consultant

-- "Michael was a great and wonderful artist and performer. We were privileged and honored to record him and his brothers here at Philadelphia International Records. We are very honored to have been a part of Michael Jackson's music and creative career in helping to write and produce his own music with his brothers. We know his music and legacy will live on for a very long time."
--Kenny Gamble and Leon Huff, producers and co-writers for the Jacksons

-- "I can't find the words right now to express how deeply saddened I am by Michael's passing. We have lost a genius and a true ambassador of not only pop music but of all music. He has been an inspiration to multiple generations and I will always cherish the moments I shared with him on stage and all of the things I learned about music from him and the time we spent together. My heart goes out to his family and loved ones."
--Justin Timberlake

-- "The incomparable Michael Jackson has made a bigger impact on music than any other artist in the history of music. He was magic. He was what we all strive to be. He will always be the King of Pop! Life is not about how many breaths you take, but about how many moments in life that take your breath away. For anyone who has ever seen, felt, or heard his art, we are all honored to have been alive in this generation to experience the magic of Michael Jackson. I love you Michael."
--Beyonce Knowles

-- "His was a rare talent that we witness once in a lifetime. One who makes such an indelible mark that for generations, singers and dancers attribute him as inspiration. I had the great privilege of watching him every night doing what he did best - entertain. I am grateful to have known him for the two years I worked for him and will mourn his loss with his many millions of fans across the world."
--Sheryl Crow, who sang on the "Bad" tour

-- "He was a highly professional entertainer who never left anything to chance. In the '80s I worked together with Michael Jackson and I will never forget his appearance in front of the Brandenburg Gate in Berlin in 1988."
--Willy Ehmann, former promotion coordinator for CBS in Frankfurt and current SVP for Sony Music in Munich

-- "For Michael Jackson the word superstar was invented. He is the King of Pop."
--Edgar Berger, CEO Sony Music Entertainment GSA (Germany, Switzerland, Austria) in Munich

-- "There was a big difference between the artist on stage and the private Michael Jackson who was very shy and reserved. Maybe the old saying is right that 'God takes those early who he loves most.' After John Lennon, Elvis and Jimi Hendrix, now Michael."
--Heinz Canibol, former marketing director of CBS in Frankfurt and current owner and CEO of the Label 105 music in Hamburg

-- "During the 25 years of our cooperation six managers came and left. I stayed. He regarded me as his older brother and he trusted me."
--Concert promoter Marcel Avram in Munich

-- "Listening to his music really inspired me to write songs that impact the world in a positive way. He also gave me confidence as a performer: watching his live shows on video, it was clear that the way he touched every person had nothing to do with his size - he's skinny like I've always been - and everything to do with his confidence and energy and absorbing that was a real turning point for me."
--Lira, Afro-soul solo artist, signed to Sony Music Entertainment Africa

-- "Michael Jackson was one of the most magnetic and talented artist I ever met. He has created the most brilliant soundtrack for the 'pop era' and will be impossible to replace. His unique songs and his extraordinary contribution to the development of a completely new way of defining the show business will be an inestimable legacy for all of us."
--Simone Bosé, director general at EMI Spain

-- "Michael Jackson was huge in Italy and the fact that today the Internet is virtually jammed with the news of his death says it all: he was a universal artist. Not even the death of [Jackson's friend] Luciano Pavarotti in 2007 had such a massive multi-media reaction in Italy."
--Enzo Mazza, president of the IFPI-affiliated body FIMI, which
represents Italy's major labels

-- "I join with my colleagues at Epic Records and Sony Music, along with music fans all over the world, in mourning the loss of my dear friend Michael Jackson. I had the privilege of working closely with Michael over a 15 year period, which culminated in the release of History: Past, Present and Future, Book 1, the top selling multiple disc release of all time. Michael gave us all the greatest gift: extraordinary, timeless music that transcended the norm and resonated with people all over the planet. From heartland America to the favelas of urban Rio de Janeiro, his heart, soul, and creative energy brought unbridled joy to the world's music fans. All at Epic Records and Sony Music were privileged to bring that music to the people with the passion one feels when delivering a heartfelt gift to a loved one. My wife Ann and I offer our deepest sympathy and condolences to Michael's three children, his family, and the entire world of music fans brought together as one by Michael Jackson's legendary musical and creative genius. He will be sorely missed."
--David R. Glew, retired Chairman of Epic Records

-- "Michael was a great and wonderful artist and performer. We were privileged and honored to record him and his brothers here at Philadelphia International Records. We are very honored to have been a part of Michael Jackson’s music and creative career in helping to write and produce his own music with his brothers. We know his music and legacy will live on for a very long time."
-- Producers Gamble and Huff

-- "My mother, Rev. Cassandra Mack, took me to my first concert at Madison Square Garden as a child to see the Jackson 5. At that moment I knew what I wanted to do after seeing the greatest entertainer of ALL TIME, Mr. Michael Joseph Jackson. I, along with the rest of the world, felt as though we were part of MJ's life because he shared his craft and gift with everyone so unselfishly. We loved you, we Love you, and we will continue to celebrate your genius until the end of time. My condolences to his family during this difficult and devastating time. Mr. & Mrs. Jackson (Joseph & Katherine) as well as his brothers, sisters and children, comfort and blessings.”
-- Al B. Sure

-- "There will never be another Michael Jackson. As a singer, song writer, businessman and, most importantly, as a humanitarian, he left an indelible imprint on the world of entertainment."
-- Kendall Minter, Rhythm & Blues Foundation chairman

-- "I am shocked, saddened and still in disbelief over the death of Michael Jackson. He was one of, if not THE greatest entertainer of all time, and was without question the ‘King of Pop.’ He was also my friend. He recorded a song of mine on his 1979 ‘Off The Wall’ album and in 1981 we sang a duet together. We spent a considerable amount of time together in 2001 at my home music studio and I saw him in a totally different light - as a nurturing and caring father. I was so honored that he dedicated that album to me. My heart and prayers are with his family, his three children, my friend Elizabeth Taylor, and all us who are mourning the premature loss of his very precious life."
-- Oscar-winning songwriter Carole Bayer Sager

-- "My experiences working with Michael have shaped the way I make music. His standards of excellence and creative drive have motivated and inspired me to do my best work. Besides being a tireless worker and a visionary, Michael was very generous and gracious in the way he treated those around him. My memories of him and how he worked will remain as fresh in my mind as do his timeless songs and incredible voice."
-- Harvey Mason, Jr.
