Red Hot Chili Peppers are 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 rock and psychedelic rock. When played live, they incorporate many aspects of jam band due to the improvised nature of much of their performances. Currently, the band consists of founding members Anthony Kiedis and Michael "Flea" Balzary, longtime drummer Chad Smith, and guitarist Josh Klinghoffer, who joined in late 2009, following the departure of John Frusciante. Red Hot Chili Peppers have won seven Grammy Awards, and have become one of the best-selling bands of all time, selling over 80 million records worldwide. In 2012, they were inducted into the Rock and Roll Hall of Fame. The band's original line-up featured guitarist Hillel Slovak and drummer Jack Irons, alongside Kiedis and Flea.
Because of commitments to other bands, Slovak and Irons did not play on the band's debut album, The Red Hot Chili Peppers. Cliff Martinez was the drummer for the first two records, and guitarist Jack Sherman played on the first. Slovak performed on the second and third albums by the band, Freaky Styley and The Uplift Mofo Party Plan; he died of a heroin overdose in 1988. As a result of the death of his friend, drummer Irons chose to depart from the group. Parliament-Funkadelic guitarist DeWayne McKnight was brought in to replace Slovak though his tenure was short and he was replaced by John Frusciante in 1988. Former Dead Kennedys drummer D.H. Peligro was brought in to replace Irons though after a short tenure with the band he was out and replaced by Chad Smith that same year. The line-up of Flea, Kiedis, Frusciante and Smith was the longest-lasting, and recorded five studio albums starting with 1989's Mother's Milk. In 1990, the group signed with Warner Bros. Records and recorded under producer Rick Rubin the album Blood Sugar Sex Magik, which became the band's first commercial success. Frusciante grew uncomfortable with the success of the band and left abruptly in 1992, in the middle of the world tour.
