What began as a mentor-upstart relationship has turned into a beautiful partnership for veteran entertainment attorney Grubman, who launched his practice in 1974, and the firm's music department head Meiselas, who came in with Sean Combs as a client in 1997. While the business of music has shrunk, GSM's roster has grown, expanding into film, TV, tech and fashion -- plus building on its music base by representing both artists (Bruce Springsteen, Elton John, Madonna, Lady Gaga) and executives (Universal's Lucian Grainge, Sony's Doug Morris) in addition to corporate clients like Live Nation, Madison Square Garden and the three major labels.
OVERUSED WORD: "'Sechel.' [It's a Hebrew word] that means a combination of instinct, balls, intellect and common sense. Very few people have all those elements in one." -- Grubman
HARDEST BUSINESS LESSON LEARNED: "In the words of Allen Grubman, 'It's not about the money, it's about the money.'" -- Meiselas
