Jackson's last rehearsal, filmed on the eve of his death and recorded in multi-camera, high-definition video, could be released as the performer's last album, according to several sources close to the now-defunct concert tour.

The recordings were made as part of concert promotion company AEG Live's deal with Jackson, which included a plan to produce both an album and DVD of what Jackson had billed his "final performance" tour, titled "This Is It."

The recordings also could be used to produce both a DVD or Blu-ray disc of the entertainer's last performance – the entertainer singing his greatest hits.

One AEG official is reported to have boasted to a colleague: "We have a live album in the can."

The rehearsal, which went on for several hours, included dancers, musicians and aerial performers. Patrick Woodroffe, lighting designer, watched the final rehearsal. He said: "We had rehearsed for the last couple weeks.

We put together a complicated show, quite a spectacular show. Of course a huge part of it was him, and I would say for the last week he hadn't really been with us. He would appear, and he would rehearse sometimes, and he would not rehearse." Randy Phillips, president of AEG Live, has refused to comment for the story.
