John Anthony Frusciante ( ; born March 5, 1970) is an American musician who is the guitarist of the Red Hot Chili Peppers across three stints. He has released over a dozen solo albums and 9 EPs, ranging in style from acoustic guitar to electronic music. He was inducted into the Rock and Roll Hall of Fame as a member of the Red Hot Chili Peppers in 2012. Rolling Stone named Frusciante among the greatest guitarists of all time.

Frusciante joined the Chili Peppers at the age of 18 after the death of the guitarist Hillel Slovak, and first appeared on their album Mother's Milk (1989). His second album with the band, Blood Sugar Sex Magik (1991), was their breakthrough success. Overwhelmed by the popularity, he quit in 1992. He became a recluse and entered a period of heroin addiction, during which he released his first solo recordings: Niandra LaDes and Usually Just a T-Shirt (1994) and Smile from the Streets You Hold (1997). In 1998, he completed drug rehabilitation and rejoined the Chili Peppers, taking them to major success with their albums Californication (1999), By the Way (2002) and Stadium Arcadium (2006). Frusciante left the Chili Peppers again in 2009 and rejoined them in 2019, recording the albums Unlimited Love (2022) and Return of the Dream Canteen (2022).

Frusciante's solo work encompasses genres including experimental rock, ambient music, and electronica. He released six albums in 2004, each exploring different genres and recording techniques. In 2009, Frusciante released The Empyrean, which features members of the Chili Peppers. Frusciante also releases acid house under the alias Trickfinger. With the ex-Chili Peppers guitarist Josh Klinghoffer and Joe Lally, Frusciante has released two albums as Ataxia.

Early life and education John Anthony Frusciante was born in Queens, New York City on March 5, 1970. His father, John Augustus Frusciante, is a Juilliard-trained pianist, who later became a lawyer and then circuit court judge in Florida. His mother, Gail Bruno, was a promising vocalist who gave up her career to be a stay-at-home mother. Frusciante is of Italian ancestry; his great-grandfather, Generoso Frusciante, was originally from Benevento.

Frusciante's family moved to Tucson, Arizona, and then Florida, where his father served as a Broward County judge until October 2010. His parents separated when he was seven years old, and he and his mother moved to Santa Monica, California.

A year later, Frusciante and his mother moved to Mar Vista, Los Angeles, with his new stepfather, whom he says, "really supported me and made me feel good about being an artist." He became involved in the Los Angeles punk rock scene. At age nine, he became fixated on the Germs, repeatedly listening to their album (GI). He later used a non-standard tuning of his own invention to play songs from the album single-finger barre.

Frusciante began studying guitarists such as Jeff Beck, Jimmy Page, and Jimi Hendrix at 11. He discovered Frank Zappa, whose work he would study for hours. He dropped out of high school at age 16 with the permission of his parents and upon completion of a proficiency test. With their support, he moved to Los Angeles to develop his musicianship. He began taking classes at the Guitar Institute of Technology, but turned to punching in without actually attending and left shortly thereafter.

Career 1988–1992: First term with the Red Hot Chili Peppers Frusciante discovered the Red Hot Chili Peppers around 1984 when his guitar instructor was auditioning as a guitarist for them. Frusciante attended a Red Hot Chili Peppers performance at age 15 and rapidly became a devoted fan. He idolized their guitarist, Hillel Slovak, familiarizing himself with virtually all the guitar and bass parts from the Red Hot Chili Peppers' first few records. He became acquainted with Slovak, and the two spoke months before Slovak's death. Frusciante told him he would not like the band if they became popular enough to play the Forum, Inglewood, and preferred smaller audiences.

Frusciante became friends with the former Dead Kennedys drummer D. H. Peligro in early 1988. They jammed together, and Peligro invited his friend, the Red Hot Chili Peppers' bassist Flea. Frusciante and Flea had an immediate musical chemistry.Mother's Milk 2003 reissue liner notes Around the same time, Frusciante intended to audition for Frank Zappa, but changed his mind as Zappa strictly prohibited illegal drug use. Frusciante said, "I realized that I wanted to be a rock star, do drugs and get girls, and that I wouldn't be able to do that if I was in Zappa's band."

Slovak died of a heroin overdose in 1988. Devastated, the Red Hot Chili Peppers drummer, Jack Irons, left the group. The remaining members, Flea and the vocalist, Anthony Kiedis, recruited Peligro on drums and DeWayne "Blackbyrd" McKnight, formerly of Parliament-Funkadelic, on guitar.Kiedis, Sloman, 2004. p. 234 However, McKnight failed to connect musically with the group. Flea proposed auditioning Frusciante, whose intimate knowledge of the Red Hot Chili Peppers' repertoire impressed him. Flea and Kiedis auditioned him and agreed that he would be a suitable replacement for McKnight.Kiedis, Sloman, 2004. p. 239 When Flea called Frusciante with the news of his acceptance, Frusciante ran through his house screaming with joy and jumped on a wall, leaving permanent boot marks. He turned down a contract with Thelonious Monster, with whom he had been playing for two weeks, to accept the Chili Peppers offer.Forsythe, Tom. (February 1991) "Laughing All the Way". Guitar Magazine.

Frusciante was not familiar with the funk genre of Red Hot Chili Peppers' sound, saying, "I wasn't really a funk player before I joined the band. I learned everything I needed to know about how to sound good with Flea by studying Hillel's playing and I just took it sideways from there."Apter, 2004. p. 181 Several weeks after Frusciante joined, Peligro, whose performance was suffering due to extreme drug abuse, was fired.Kiedis, Sloman, 2004. p. 242 Chad Smith was recruited as the drummer and the new lineup began recording their first album, Mother's Milk (1989). Frusciante focused on emulating Slovak's style. The producer, Michael Beinhorn, disagreed with this approach and wanted Frusciante to play with an uncharacteristic heavy metal tone, largely absent from the band's three preceding records.Kiedis, Sloman, 2004. p. 249 Frusciante and Beinhorn frequently fought over guitar tone and layering; Beinhorn prevailed, as Frusciante felt pressured by his knowledge of the studio. Kiedis recalled that "[Beinhorn] wanted John to have a big, crunching, almost metal-sounding guitar tone whereas before we always had some interesting acid-rock guitar tones as well as a lot of slinky, sexy, funky guitar tones".Kiedis, Sloman, 2004. pp. 239–241

The Chili Peppers collaborated with producer Rick Rubin for their second record with Frusciante, Blood Sugar Sex Magik (1991). Rubin felt that it was important to record the album in an unorthodox setting and suggested an old Hollywood Hills mansion.Kiedis, Sloman, 2004. p. 284 Frusciante, Kiedis and Flea isolated themselves there for the duration of the recording. Frusciante and Flea seldom went outside and spent most of their time smoking marijuana.Dalley, Helen (August 2002). "John Frusciante" Total Guitar. Retrieved on August 27, 2007. Around this time, Frusciante began a side project with Flea and the Jane's Addiction drummer Stephen Perkins, the Three Amoebas. They recorded roughly 10 to 15 hours of material, which went unreleased.

1992: First departure from the Chili Peppers Blood Sugar Sex Magik reached number three on the Billboard charts and went on to sell 13 million copies worldwide. The unexpected success turned the Red Hot Chili Peppers into rock stars. Frusciante was blindsided by his newfound fame and struggled to cope. Soon after the album's release, he began to develop a dislike for the band's popularity. He and Kiedis argued after concerts: "John would say, 'We're too popular. I don't need to be at this level of success. I would just be proud to be playing this music in clubs like you guys were doing two years ago.'"Kiedis, Sloman, 2004. p. 229 Frusciante later said that the band's rise to popularity was "too high, too far, too soon. Everything seemed to be happening at once and I just couldn't cope with it."

Frusciante also began to feel that destiny was leading him away from the band. When the Red Hot Chili Peppers began their world tour, he started to hear voices in his head telling him "you won't make it during the tour, you have to go now". Frusciante said he had once taken pleasure in hedonism; however, "by the age of 20, I started doing it right and looking at it as an artistic expression instead of a way of partying and screwing a bunch of girls. To balance it out, I had to be extra-humble, extra-anti-rock star.""The Chili Peppers Rise Again". Rolling Stone. Retrieved on August 8, 2007 He refused to take the stage during a performance at Saitama Sonic City on May 7, 1992, telling his bandmates that he was leaving the band. He was persuaded to perform but left for California the next morning. "It was just impossible for me to stay in the band any longer," he said. "It had come to the point where even though they wanted me in the band, it felt like I was forced out of the band. Not by any members in particular or management in particular, but just the direction it was going."Broxvoort, Brian (1994). "John Frusciante Goes Over a Bridge." Rockinfreakapotamus. He was replaced by the former Jane's Addiction guitarist Dave Navarro.

In a 2015 interview, Cris Kirkwood said that following Frusciante's departure from the band in 1992, Frusciante auditioned for the Meat Puppets. Kirkwood said, "He showed up with his guitar out of its case and barefoot. We were on a major label then, we just got signed, and those guys had blown up to where they were at and John needed to get out. John gets to our pad and we started getting ready to play and I said, 'You want to use my tuner?' He said, 'No, I'll bend it in.' It was so far out. Then we jammed but it didn't come to anything. Maybe he wasn't in the right place and we were a tight little unit. It just didn't quite happen but it could have worked."

1992–1997: Addiction and first solo albums Frusciante had developed serious drug habits while touring with the Chili Peppers; he said that when he "found out that Flea was stoned out of his mind at every show, that inspired me to be a pothead".Kennealy, Tim (July 1995). "Chilly Pepper". High Times. He used heroin and was on the verge of full-scale addiction. Upon returning to California in 1992, Frusciante entered a deep depression, feeling that his life was over and that he could no longer write music or play the guitar. He spent the next three years in his Hollywood Hills home, the walls of which were badly damaged and covered in graffiti. During this time, his friends Johnny Depp and Gibby Haynes went to his house and filmed a documentary short, Stuff, depicting the squalor in which he was living. The house was eventually destroyed by a fire that also destroyed Frusciante's vintage guitar collection and several recordings.Di Perna, Alan (July 2006). "Guided by Voices". Guitar World.

Frusciante focused on painting, producing 4-track recordings he had made while working on Blood Sugar Sex Magik and writing short stories and screenplays. To cope with his worsening depression, Frusciante increased his heroin use and spiraled into a life-threatening dependency. His use of heroin to medicate his depression was a clear decision: "I was very sad, and I was always happy when I was on drugs; therefore, I should be on drugs all the time. I was never guilty—I was always really proud to be an addict."Sullivan, Kate (August 2002). "Interview with Flea, Anthony and John". Spin.
