“In the Back” is one of Jackson’s most impressive unreleased tracks from the 1990s. Atmospheric and hypnotic, it recalls Jackson’s Dangerous-era masterpiece “Who Is It” (and touches on similar themes of betrayal). The track begins with an ominous, thudding beat, accented by Jackson’s vocal percussion. Jackson sings and scats his way through the vocal (which was left finished). Brad Buxer pointed out that he spent years developing the song—first during the HIStory sessions, then for Blood on the Dance Floor, and finally for Invincible.
What begins as a minimalist groove gradually unfolds into an intricate and ethereal sonic canvas—lush strings, an entrancing harp, and a mournful trumpet. Buxer described the track as “unbelievable and it proves once again how Michael was a genius. I play almost every instrument on this song, but all [the] ideas are Michael.” The 1997 demo, recorded in Switzerland, was released on Michael Jackson: The Ultimate Collection in 2004.
