Michael Jackson's family will stage a star-studded tribute concert for him in October.

The late 'Thriller' hitmaker - who passed away from acute Propofol intoxication in June 2009 - will be remembered in a four-hour performance extravaganza to be held at the Millennium Stadium in Cardiff, Wales, his mother Katherine and siblings Latoya, Tito, Jackie and Marlon announced in a press conference at the Beverly Hills Hotel today (25.07.11).

No artists have yet been announced for 'Michael Forever: The Tribute Concert' - which will be held in front of 75,000 fans - but it is expected that performers will be revealed daily until August 4, when tickets will go on sale.

However, Tito promised the concert will feature "all the artists [Michael] admired and respected so much.

"Michael loved doing things on a large, major scale. This is definitely one that he would approve."

Global Live Events, who are staging the concert, promised it will be a fitting tribute to the King of Pop's musical legacy.

Chris Hunt, president of Global Live Events, said: "We wanted to do something decent and worthy of Michael's musical genius yet something fun and authentic that you would envision Michael attending with excitement and joy surrounded by talent that he respected and loved."

It's intended that the concert will raise awareness and funds for Aids Project Los Angeles and two other charities to be announced later.

It was not explained why Michael's siblings Janet, Jermaine and Randy were not in attendance at the press conference, but his brothers later blasted the "inappropriate" timing of the concert, which is scheduled to take place less than three weeks after the start of Dr. Conrad Murray's trial for the involuntary manslaughter of the singer.

Jermaine and Randy said: "While we wholeheartedly support the spirit of a tribute that honours our brother, we find it impossible to support an event that is due to take place during the criminal trial surrounding Michael's death.

"There will come a time and place for an amazing and deserving tribute to Michael. But we feel that the most important tribute we can give to our brother at this time is to seek Justice in his name."
