Blood Sugar Sex Magik is the fifth studio album by American rock band Red Hot Chili Peppers, released on September 24, 1991, by Warner Bros. Records. Produced by Rick Rubin, its musical style differed notably from the band's previous album Mother's Milk (1989), reducing the use of heavy metal guitar riffs and accentuating the melodic songwriting contributions of guitarist John Frusciante. The album's subject matter incorporates sexual innuendos and references to drugs and death, as well as themes of lust and exuberance.
