Michael Jackson left behind an abundance of recently recorded videos of his performances, according to various news reports, including high-quality footage of rehearsals for his “This Is It” comeback concerts in London and a top-secret music video dubbed the “Dome Project” that Jackson wrapped shooting just two weeks before his death. and The Hollywood Reporter are reporting that “This Is It” concert producer AEG Live has gathered 100 hours of video of Jackson and his rehearsals for his 50 scheduled London comeback shows, including a multi-camera, high-definition production shot the night before he died and enough audio for as many as two live albums. AEG, however, declined to comment to EW about whether they planned to release DVDs of the footage. Meanwhile, the Associated Press is reporting that Jackson shot the “Dome Project” for several days in early June, on four sets in the Culver Studios in L.A., including one set reminiscent of Jackson’s iconic “Thriller” video. The project is reportedly expected to be completed July 15, but it is unclear when or whether it would see the light of day.
