Flea is also a member of the supergroups Atoms for Peace, Antemasque, Pigface, and Rocket Juice & the Moon, and has played with acts including the Mars Volta, Johnny Cash, Tom Waits, Alanis Morissette, Young MC, Nirvana, What Is This?, Fear, and Jane's Addiction.

[24] Peligro, the former drummer of the punk rock band Dead Kennedys, was a friend of John Frusciante, an 18-year-old guitarist and avid Red Hot Chili Peppers fan.

It was the first time we went in to make a record where there wasn't this feeling of being sort of intimidated by what was going to happen.When Blood Sugar Sex Magik was released on September 24, 1991, it received an extremely positive critical response.

[37] The massive attention the Chili Peppers started receiving, however, caused Frusciante to feel extremely uncomfortable, and he abruptly quit the band during the Japanese leg of the album's tour,[38] replaced temporarily by Arik Marshall.

He performed on over forty records from 1995 to 1998, ranging from Alanis Morissette's Jagged Little Pill (with Navarro) to former Minutemen bassist Mike Watt's debut solo album Ball-Hog or Tugboat?.

When Californication was released on June 8, 1999, it received overwhelmingly positive critical reviews and sold fifteen million copies worldwide—more than Blood Sugar Sex Magik.

"[71] On April 9, 2014, it was revealed that Flea was working on a new musical project, the band Antemasque, with former Mars Volta members Cedric Bixler-Zavala, Omar Rodríguez-López, and Dave Elitch.

The original scope of the book was to chronicle Flea's unconventional childhood (including his move from a "normal" life in the New York suburbs to a "bohemian" lifestyle in Los Angeles with his jazz-playing stepfather), his adventures in the L.A. streets, his "sometimes complex friendship and collaboration" with Chili Peppers co-founder Anthony Kiedis and the overall "tumultuous creative journey" of the band, which formed in 1983.

[76] The Chili Peppers began working on their twelfth studio album in the summer of 2020; however, due to the COVID-19 pandemic, there were delays in the writing and recording, with their 2020 tour dates being postponed until 2021.

The tour includes the band's first-ever headlining stadium shows in the United States[79] in support of their twelfth and thirteenth studio albums, Unlimited Love and Return of the Dream Canteen, which were respectively released on April 1 and October 14, 2022.

He played a number of minor roles in films throughout the 1990s, including Son in Law (1993) as a tattoo artist, The Chase (1994) as a monster truck driver alongside Kiedis, Fear and Loathing in Las Vegas (1998) as a "Hippie", in The Big Lebowski (1998) as a German nihilist,[83] and the 1998 remake of Psycho.

The documentary, which was directed by Andrea Blaugrund Nevins, focused on a generation of punk rockers, how they have handled fatherhood, and how they went from public rebel to domestic authority figure.

Flea said when he turned 30 he was living a crazy life and got really sick with chronic fatigue due to non-stop partying and drugs and it was through the discovery of a self-help book by Jon Kabat-Zinn that led him down this path.

[citation needed] The Chili Peppers were invited by the Beastie Boys and the Milarepa Fund to perform at the Tibetan Freedom Concert in June 1996 in San Francisco.

[114] In October 2008, Flea (along with his daughter Sunny Bebop) appeared in a Vote for Change ad voicing his support for Barack Obama for president of the United States in the upcoming election.

"[117] On September 18, 2015, Flea and his Chili Peppers bandmates were among over 120 entertainers and celebrities to announce that they would be voting for Bernie Sanders in the 2016 election for President of the United States.

The Red Hot Chili Peppers have been great supporters of the Tibetan cause, of His Holiness the Dalai Lama, and of the need to work to protect and preserve our environment."

Flea wrote "Dear plains all American pipeline, my daughter just dared step on the beach for a few minutes where we live about 75 miles from the Santa Barbara oil spill you caused.

Flea stated he can no longer surf there or take his daughter to the beach further saying "Some kid in the hood who made a mistake selling drugs will go to jail and have his life ruined but you, you evil lying scumbags will get away with a paltry fine that means nothing to you.

Days later the Red Hot Chili Peppers performed at a benefit concert for victims of recent deadly Woolsey Fire in California which killed four people and destroyed over 1,500 homes.

[140] Flea has occasionally performed a bass rendition of "The Star-Spangled Banner" before games of the Los Angeles Lakers at the Crypto.com Arena (formerly called Staples Center) in a similar manner as Jimi Hendrix.

[142] Flea has employed a wide variety of basses over his career with some varying exclusivity, such as Music Man, Modulus, his own brand Fleabass, and Fender Jazz and Precisions.

[161] Flea has displayed a wide variety of techniques throughout the years, ranging from his initial use of slapping and popping to the more traditional methods he has employed since Blood Sugar Sex Magik.

Greg Prato of Allmusic wrote that "by combining funk-style bass with psychedelic, punk, and hard rock, Flea created an original playing style that has been copied numerous times".

[162] Smashing Pumpkins front man Billy Corgan recalls, that when he first saw the Chili Peppers in 1984, "Flea was playing so aggressively that he had worn a hole in his thumb and he was literally screaming in pain in-between songs because it hurt so bad.

[15] However, this technique caused Flea to receive attention from the music world and was often copied, and he, therefore, felt it necessary to almost completely remove slap-bass styles from his repertoire following Mother's Milk (1989).

"[164] This led Flea to alter the way he wrote music by playing alone, instead of the jam sessions that would dictate how the band conceived songs: "[One Hot Minute] is the least jam-oriented record we've made.

[4][14][17] Flea credits his continued interest in music to jazz performers like Jaco Pastorius, Miles Davis, Duke Ellington, Charlie Parker, Louis Armstrong, John Coltrane, and Dizzy Gillespie.

Originally, Flea was given the impression by punk bands, that one should play as hard and fast as they possibly could, but ultimately rejected this philosophy during Blood Sugar Sex Magik: "I was so into being raw [...] it was all bullshit.

[168] In April 2011, Flea was voted the second-best rock bassist in a poll conducted by Contact Music, behind Entwistle and ahead of McCartney, Geddy Lee of Rush and Les Claypool of Primus.
