LOS ANGELES (AP) — A 30-second snippet of Michael Jackson rehearsing two days before his death was released Thursday, part of more than 100 hours of footage that could be turned into live albums, a movie and a pay-per-view special, the promoter said.

The treasure trove of material, along with possible insurance proceeds and ticket sales to memorabilia collectors, could help benefit the late singer's estate, which is burdened by an estimated $400 million in debt.

"He was our partner in life and now he's our partner in death," Randy Phillips, president and CEO of concert promoter AEG Live, said in an interview at Staples Center.

Jackson had been rehearsing for a giant series of comeback shows in London.

"If we all do our jobs right, we could probably raise hundreds of millions of dollars just on the stuff we have worldwide and then the estate could eradicate its debt."

AEG Live also stands to profit from the material. Jackson's album sales have exploded since his death, with three of his albums in the top three spots and 2.3 million tracks downloaded in the United States, Nielsen SoundScan said. Worldwide digital downloads for the week hit 3.3 million.

The clip released Thursday shows Jackson dancing and singing to "They Don't Really Care About Us" on June 23 during a rehearsal at Staples Center. He died two days later at age 50.

Phillips said he released the clip because he was tired of seeing the singer negatively portrayed in the media since his death.
