Arrested Development was formed in 1988 by rap vocalist Todd Thomas ("Speech") and turntablistTimothy Barnwell ("Headliner"). The group's debut album, 3 Years, 5 Months & 2 Days in the Life Of..., was the number-one album in the Village Voice's 1992 Pazz and Jop Critic's Poll and in The Wire's 1992 Critic's choice. The group won two Grammy Awards in 1993 for Best New Artist and Best Rap Performance by a Duo or Group, and were also named Band of the Year by Rolling Stone magazine.
A few months later, the group was approached by film director Spike Lee, to compose a song for his upcoming biopic based on the life of Malcolm X. The group then recorded "Revolution", which appeared on the oldies-dominated soundtrack for the film, as well as the second half of its closing credits when the film was released in 1992.
