Several members of Michael Jackson's family held a press conference in Beverly Hills on Monday (July 25) morning to announce a tribute concert for their brother, who died two years ago. Aside from a location, a date and a name for the event, the famous family played coy with the details.

Set for Oct. 8, "Michael Forever: The Tribute Concert" will take over Millennium Stadium in Cardiff, Wales, where organizers Global Live Events hopes to attract 75,000 fans. Just what fans will be hearing will be announced online in small increments over the next two weeks. Tickets go on sale on Aug. 4.

The King of Pop's siblings Marlon, Jackie, Tito and La Toya, as well as family matriarch Katherine, attended the announcement. The 81-year-old Katherine said the concert would be a "world-class event" and a fitting tribute to her son, who died in 2009 at age 50.

Michael's brothers did not take questions at the announcement and would not confirm if they would be performing. According to Global Live Events, the concert will be broadcast over the Web live in both 2D and 3D.

"I know my brother would be very, very proud to see all the artists that he admired and respected so much coming together for this event," Tito Jackson said.

La Toya Jackson promised that the "tribute will be something that's spectacular."

Father Joe and siblings Janet, Jermaine and Randy were not in attendance.

Before fans can get too excited about traveling to Wales, there may be a legal fight ahead. The executor's of Michael Jackson's estate have not been approached about the use of the singer's name, estate spokesman Jim Bates told CNN shortly after the press conference.
