Ron Wynn from AllMusic gave the album 4.5 out of 5 stars stating, When an act called Sisters Love were offered a cameo in the blaxploitation film The Mack, their manager suggested that Willie Hutch do the soundtrack. It came to be one of the great '70s film scores, including a pair of classic funk tunes, "Brothers Gonna Work It Out" and the title cut. The results proved to be another soundtrack that far surpassed the quality of its film.[1]
On May 5, 1973, the song from the soundtrack, Brother's Gonna Work It Out, first appeared at No. 47 on the Hot Soul Singles chart.[2] It peaked at No. 18, on June 21, 1973, as reported from Jet.[3] On September 15, 1973, Slick, appeared at No. 65 on the same chart,[4] as it did on August 25, 1973,[5] at No. 81, and on September 1, 1973, at the same position.[6] On September 22, 1973, it peaked at No. 23 on the same chart the next week shortly after peaking at No. 65.[7]
