Los Angeles ( CNN ) -- Michael Jackson 's mother and four of his siblings announced Monday a tribute concert for the late pop singer to be held in Wales in October , but the lineup for talent is still a secret . Brothers Marlon , Tito and Jackie , sister La Toya and family matriarch Katherine Jackson attended the `` Michael Forever The Tribute Concert '' announcement at the Beverly Hills Hotel on Monday morning . But the announcement exposed a major rift among members of the Jackson family , especially with Jackson brothers Jermaine and Randy , who did not attend the news conference . They objected to the show because it 's scheduled to happen during the criminal trial of the doctor accused in Michael Jackson 's death . `` We want to make clear that this does not reflect the position of the entire family , '' the two brothers said in a joint statement . `` While we wholeheartedly support the spirit of a tribute that honors our brother , we find it impossible to support an event that is due to take place during the criminal trial surrounding Michael 's death , '' they said . While the head of the British company promoting the show , Global Events Live , hinted it could include a Jackson brothers reunion , the statement from Jermaine and Randy Jackson on Monday indicated that would not happen . `` In light of this , we feel it is inappropriate to be involved with such an ill-timed event and its promoter , Global Live , '' Randy and Jermaine Jackson said . Their statement said the idea of the October concert was presented to the entire family in April `` as an idea already in its advanced stages . '' The decision to go ahead with it `` disrespects opinions and wishes expressed in the strongest terms '' by some members of the Jackson family , they said . La Toya Jackson said the `` tribute will be something that 's spectacular '' and is `` far , far , well overdue . ' The Jacksons ' mother called it `` a show fit for a king , '' `` If my son were here today , he would feel the same way , '' Katherine Jackson said . Executors for the late pop singer 's estate were unaware of the planned tribute , estate spokesman Jim Bates told CNN . `` The estate has not been contacted and is not involved with Global Live Events in the UK tribute concert announced today , '' he said . The show will `` feature the world 's most amazing music performers , '' according to the head of British promoter Global Live . The roster will be revealed online one act at a time over the next two weeks , starting Tuesday , Chris Hunt said . All profits from the show would go to several U.S. and British charities , including a cancer group created by the prince of Wales , Hunt said . The October 8 show , in the Wales Millennium Centre in Cardiff , Wales , would be at least four hours long , Hunt said . The venue will seat up to 75,000 people , he said . `` 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 . Hunt presented the Jackson family with a $ 100,000 check that will go to a trust fund for Michael Jackson 's three children , which they can access when they turn 21 . The children , Katherine Jackson and unidentified charities are the sole beneficiaries of Jackson 's wealthy estate .
Jackson brothers Randy and Jackson call the tribute ill-timed . The tribute is `` far , far , well overdue , '' Jackson says . La Toya Jackson 's mother , sister and up to 75,000 brothers made the announcement . Jackson estate executors have not authorized the show , a spokesman says .
