The next big thing to happen to southern soul in the 1960s was Isaac Hayes' extended orchestral raps, that debuted on Presenting (1967) with a lengthy cover of Erroll Garner's Misty, and that matured on the four-song album Hot Buttered Soul (1969), including colossal covers of Jimmy Webb's By The Time I Get To Phoenix and Burt Bacharach's Walk On By. Movement (1970) was more of the same: four lengthy covers, including George Harrison's Something. This style of subdued singing and lavish production was further revolutionized by the soundtrack to the film Shaft (1971), that added a strong funky undercurrent.

Black Moses (1971) was another ambitious (double) album.

He then tried to stay up to date with albums such as: Joy (1973), Use Me (1975), Chocolate Chip (1975), Groove-A-Thon (1976), Juicy Fruit (1976), New Horizon (1977), For the Sake of Love (1978), HotBed (1978), Don't Let Go (1979), Royal Rappin's (1979), which was a collaboration with rapper � Millie Jackson, And Once Again (1980), Lifetime Thing (1981), U-Turn (1986), Love Attack (1988), Branded (1995).

Hayes died in 2008 at 65.
