Spike Lee has explored Michael Jackson’s transition from member of the Jackson 5 to solo artist in Showtime’s upcoming documentary “Michael Jackson’s Journey From Motown To Off The Wall.”

The trailer debuted Wednesday, 11 days ahead of the film’s premiere at the Sundance Film Festival. Showtime will air the documentary on Feb. 26.

The “Off the Wall” trailer includes archival footage from concerts in 1979 and 1981 plus interviews with performers the Weeknd, David Byrne of The Talking Heads and Questlove of the Roots about Jackson’s seminal solo album.

“I’ve always used Michael as, first and foremost, a vocal inspiration, and ‘Off the Wall’ was definitely the one that made me feel like I could sing,” the Weeknd notes in the preview. “I found my falsetto because of ‘Off the Wall.'”

The film includes interviews with Pharrell Williams, Mark Ronson, John Legend, L.A. Reid, Kobe Bryant, Misty Copeland, parents Katherine and Joe Jackson and brothers Jackie and Marlon Jackson.

The doc will also be bundled with the CD/DVD reissue of “Off the Wall,” which drops Feb. 26.
