Isaac Lee Hayes, Jr., American singer-songwriter, musician, and actor (born Aug. 20, 1942, Covington, Tenn.—died Aug. 10, 2008, East Memphis, Tenn.), was a pioneering figure in soul music whose recordings influenced the development of such musical genres like disco, rap, and urban contemporary. The charismatic performer— known for his shaved head, dark sunglasses, and smooth baritone voice—was perhaps best remembered for his compelling soundtrack for the 1971 film Shaft; the title song, “Theme from Shaft,” became a number one hit and earned Hayes an Academy Award for best original song. Hayes reached his greatest popularity in the late 1960s and ’70s, placing (1969–76) 10 consecutive albums on the American pop and rhythm and blues charts. Hayes was a self-taught pianist and saxophonist. He began his professional career performing at Memphis nightclubs and was eventually hired as a session musician for Memphis-based Stax Records; he went on to become one of the label’s most successful songwriters. Although Hayes’s debut solo album, Presenting Isaac Hayes (1967), did not fare well commercially, his next release, Hot Buttered Soul(1969), sold more than one million copies and established him as a star. Among his other notable albums were Black Moses (1971), Joy (1973), Live at the Sahara Tahoe (1973), and Chocolate Chip (1975). Hayes later devoted much of his attention to acting, appearing in such movies as Escape from New York (1981), I’m Gonna Git You Sucka (1988), and It Could Happen to You (1994) and in various TV series, notably the animated hit South Park, for which he provided (1997–2006) the voice of the character Chef. Hayes released (1995) two studio albums, Raw and Refined and Branded, to generally positive reviews. He was inducted in 2002 into the Rock and Roll Hall of Fame.
