The band initially formed for a one-off support act for a friend's band, calling themselves Tony Flow And The Miraculously Majestic Masters Of Mayhem. Upon renaming themselves Red Hot Chili Peppers, they played a handful of small club venues in Los Angeles in 1983, before they were signed to EMI Records.

The Chili Peppers' original guitarist, Slovak, was replaced in 1984 by Jack Sherman, while Slovak and Irons recorded music with their band at the time, "What Is This?" Upon Slovak's return, Sherman was fired from the band.

Following Slovak's death of a heroin overdose, a young John Frusciante took over as guitarist in 1988. Frusciante, however, quit the band in 1992 due in part to his sadness at the band becoming so successful in such a short time; complex personal issues, involving an addiction to heroin, were also a factor. He was then replaced by Arik Marshall. Approximately a year later, Marshall left the band, to be replaced by former Jane's Addiction guitarist Dave Navarro.

After the release of 1995's One Hot Minute, Navarro's escalating drug habits became a subject of conflict. In 1998, Navarro was fired from the band, to be taken over by none other than former guitarist, Frusciante, who has remained in the band ever since.

Founder and guitarist Hillel Slovak did not actually appear on the self-titled debut album, despite performing and writing the content with the band prior to recording. He was replaced by Jack Sherman for the recording of the album, but returned to the band for second album, Freaky Styley. The third album, Uplift Mofo Party Plan, is in fact the only album to include all four founding members. After this, Slovak overdosed on heroin and was replaced on future albums (Mother's Milk, Blood Sugar Sex Magik - on which Frusciante provides guitars, One Hot Minute - Navarro, Californication and By the Way - Frusciante) Frusciante is also on their latest release Stadium Arcadium.

Bassist flea claims to have nearly quit following the tour for 2002 album By the Way due to feeling sidelined following Frusciante's development as a guitarist. Flea has been quoted as saying that the issue has now been resolved. Flea is also the only member to have been in the band perpetually as Anthony was kicked out for a short time in 1984 due to his drug problems.

Frusciante has also been making solo albums for a number of years. His new album with the band Ataxia came out May 2007, and is titled Automatic Writing II.

In 2003 Flea played bass on The Mars Volta's album Deloused In The Comatorium. Frusciante added guitar to tracks on Deloused and 2005's Frances The Mute. He also played rhythm guitar on The Mars Volta's Amputechture. Omar A. Rodriguez-Lopez, guitarist for The Mars Volta, appeared on Stadium Arcadium, playing the solo on "Especially In Michigan".

A new era in the band's history took place due Frusciante's departure in 2009. He was replaced by Josh Klinghoffer, who had already played shows as a second guitarist with the band during their 2007 tour dates. As of late 2009 the band is working on a new record.

Through the years, Kiedis' lyrics have dealt with a variety of topics, which have shifted as time has progressed. Themes within his expansive repertoire include love and friendship, teenage angst and good-time aggression, various sexual topics and the link between sex and music, political and social commentary (Native American issues in particular), romance, drugs, loneliness, globalization and the cons of fame and Hollywood, poverty, alcohol, and dealing with death.

Red Hot Chili Peppers is an American alternative rock band formed in Los Angeles in 1983. The band's current line-up is Anthony Kiedis (vocals), Michael "Flea" Balzary (bass), Chad Smith (drums) and Josh Klinghoffer (guitar). Their musical style has fused traditional funk with elements of other genres including hip hop, punk rock, and psychedelic rock.

The group originally featured guitarist Hillel Slovak and drummer Jack Irons. Slovak, however, died of a heroin overdose in 1988, resulting in Irons' departure. Irons was replaced briefly by former Dead Kennedys drummer D.H. Peligro before the band found a permanent replacement in Smith, while Slovak was replaced by guitarist John Frusciante. This lineup recorded the band's fourth, fifth, sixth (Dave Navarro replacing Frusciante), seventh, and eighth albums, Mother's Milk (1989),Blood Sugar Sex Magik (1991), Californication (1999), By the Way (2002), and Stadium Arcadium (2006).

Blood Sugar Sex Magik was a significant record for the band; having sold over fifteen million copies, it provided the group's initial mainstream commercial success. Frusciante grew uncomfortable with this new found success and left abruptly in the middle of the tour for the album in 1992, descending into heroin addiction. After recruiting guitarist Arik Marshall to finish the tour, Kiedis, Flea, and Smith employed Dave Navarro of Jane's Addiction for their subsequent album, One Hot Minute (1995). Although successful, it did not match the critical acclaim of Blood Sugar Sex Magik and sold less than half the copies of its predecessor. Shortly afterwards, Navarro departed the band due to creative differences. Frusciante, fresh out of drug rehabilitation, rejoined the band in 1998, at Flea's request. The reunited quartet returned to the studio to record Californication (1999), which went on to sell fifteen million units worldwide, becoming their most commercially successful album to date. It was followed three years later with By the Way (2002), which continued their success. In 2006, the group released the double album Stadium Arcadium, giving them their first American number one album.

Red Hot Chili Peppers have won seven Grammy Awards. The band has sold over 55 million albums worldwide, has had eight singles in the Top 40 of the Billboard Hot 100 (including three singles in the Top 10), five number one singles on the Mainstream Rock charts, and holds a record of eleven number one singles on the Modern Rock charts.
