The Memphis hip-hop group Three 6 Mafia(Jordon "Juicy J" Houston, Paul "DJ Paul" Beauregard and Darnell "Crunchy Black" Carlton, Cedric "Frayser Boy" Coleman), made history when they performed the first hip-hop song ever performed on an Academy Awards telecast, "It's Hard Out Here for a Pimp" (music and lyrics by Jordan Houston, Cedric Coleman, and Paul Beauregard) from HUSTLE & FLOW. Then, history was made again when the song won the Best Song of 2005. Singer Taraji P. Henson, the actress who played Shug and sang the hook (melody overlay) in the film, sang over the "boys" hip-hop vocal rhythm. The movie DVD and soundtrack CD, with the original explicit lyrics, are available. [Official Oscar Site]
