Part 1 of "Soul Power" appeared on the 1972 albumSoul Classics. Live versions of the song were included on Revolution of the Mind (1971) and Love Power Peace (1992; recorded 1971), but no longer version of the original studio recording received an album release until an eight-minute re-edit was issued on the 1986 compilation albumIn the Jungle Groove. The complete studio recording, over 12 minutes long, appeared for the first time on the 1996 CD compilation Funk Power 1970: A Brand New Thang.
In 1974, Brown created an instrumental version of "Soul Power" by having Maceo Parker and Fred Wesley overdub new horn parts onto the rhythm track of the original recording. Sound engineer Bob Both added sound effects at several points to conceal where the original horn track had bled through into the rhythm parts. Titled "Soul Power 74" and credited to "Maceo and the Macks", the new version was released as a two-part single on People Records and charted #20 R&B and #109 Bubbling Under Pop.[3] It also appeared on the album Us!.
