Red Hot Chili Peppers is an American rock band, formed in Los Angeles in 1983. The group's musical style primarily consists of rock with an emphasis on funk, as well as elements from other genres such as punk, hip hop and psychedelic rock. The band consists of founding members Anthony Kiedis (vocals) and Michael "Flea" Balzary (bass), alongside longtime drummer Chad Smith and recently added guitarist Josh Klinghoffer.
The band's original line-up featured guitarist Hillel Slovak and drummer Jack Irons, albeit not playing on the debut album, The Red Hot Chili Peppers. Cliff Martinez was the drummer for the first two records, filling in for Irons, and guitarist Jack Sherman played on the first only. Slovak performed on two albums with the band, Freaky Styley and The Uplift Mofo Party Plan; he died of a heroin overdose in 1988, resulting in Irons' departure. Former Dead Kennedys drummer D.H. Peligro briefly replaced Irons before the band found a permanent replacement in Smith. Guitarist John Frusciante replaced Slovak. The line-up of Flea, Kiedis, Frusciante and Smith was the longest-lasting, and recorded the band's fourth, fifth, seventh, eighth and ninth albums, Mother's Milk (1989), Blood Sugar Sex Magik (1991), Californication (1999), By the Way (2002), and Stadium Arcadium (2006).
