Mother's Milk is the fourth studio album by the American rock band Red Hot Chili Peppers, released on August 16, 1989, on EMI Records. After the death of founding guitarist Hillel Slovak and subsequent departure of drummer Jack Irons, vocalist Anthony Kiedis and bassist Flea regrouped with the addition of guitarist John Frusciante and drummer Chad Smith. Frusciante's influence altered the band's sound by placing more emphasis on melody than rhythm, which had dominated the band's previous material. Returning producer Michael Beinhorn favored heavy metal guitar riffs as well as overdubbing that was perceived by Frusciante as excessive, and as a result Beinhorn and Frusciante constantly fought over the album's guitar sound. The record was a greater commercial success than any of the Chili Peppers' three previous studio albums.
