I Want You Back!

Unreleased Masters is a Jackson 5 compilation released on November 10, 2009 (roughly five months after lead singer Michael Jackson's death) to celebrate the 40th anniversary of the band's debut on Motown Records; their debut single "I Want You Back" was issued October 7, 1969.

The compilation, specifically designed to fit like a regular 1970s-era album, contains previously unreleased songs and alternate versions of some of the group's hits.
