Michael Peter Balzary (born October 16, 1962), better known by his stage name Flea, is an Australian-born American musician and occasional actor. He is best known as the bassist, co-founding member, and one of the composers of the rock band Red Hot Chili Peppers. Flea is also the co-founder of Silverlake Conservatory of Music, a non-profit music education organization founded in 2001.

Originally a jazz trumpet prodigy, Flea learned to play bass in high school from close friend and future Red Hot Chili Peppers guitarist Hillel Slovak, who required a bassist for his band Anthym. Flea soon developed his own style and joined the group, but quit several months later in order to play for the punk rock outfit Fear. He then rejoined Slovak to form an intended one-off band Tony Flow and the Majestic Masters of Mayhem along with fellow high school alumni Anthony Kiedis and Jack Irons; the impromptu collaboration would ultimately give birth to the Red Hot Chili Peppers.

Highly regarded as one of the best rock bass players of all time, his work as a bassist incorporates several musical styles, ranging from aggressive slap bass to more subdued and melodic techniques. Drawing influences from funk music and punk rock, Flea centers his playing on simplicity and minimalism while viewing complexity as a device that should be used in moderation. Aside from the Red Hot Chili Peppers, he has collaborated with many artists, including Jane's Addiction, Atoms for Peace, The Mars Volta, Alanis Morissette, Johnny Cash, Young MC, P and as more recently, Rocketjuice and The Moon. Flea is ranked #2 on Rolling Stone's "Readers Pick the Top Ten Bassists of All Time". Along with his Red Hot Chili Peppers bandmates, past and present, Flea was inducted in the 2012 Rock and Roll Hall of Fame on April 14, 2012.

Michael Peter (May 7, 1949 – October 23, 1997) was a field hockey player from West Germany, who captained the West German team that won the gold medal at the 1972 Summer Olympics in Munich.

Twelve years later, at age 35, he was a member of the squad that won the silver medal at the 1984 Summer Olympics in Los Angeles, California. He was born in Heidelberg, Baden-Württemberg.

Chadwick "Chad" Gaylord Smith (born October 25, 1961) is an American musician, best known as the longtime and current drummer of Red Hot Chili Peppers whom he joined in 1988. Smith is also the drummer of the hard rock supergroup Chickenfoot, which formed in 2008.

Smith has also worked with Deep Purple vocalist Glenn Hughes' backing band and on his own instrumental side-project, Chad Smith's Bombastic Meatbats. In 2010 Smith released a children's record, Rhythm Train which he recorded with legend, Dick Van Dyke, and Leslie Bixler. In April 2010 MTV named Rhythm Train one of the best children's records of all time.

In addition to Smith's bands, he also records with many other musicians including The Dixie Chicks, Kid Rock, George Clinton and Outernational. Smith was ranked #87 on Rolling Stone list of "100 Greatest Drummers of All time". He entered the Guinness book of the world records for playing the world's largest drum kit consisting of 308 pieces. In March 2012 Modern Drummer named Smith #2 on its list of best living drummers.

Josh Adam Klinghoffer (born October 3, 1979) is an American multi-instrumentalist, who is best known as the current guitarist and backing vocalist for the rock band Red Hot Chili Peppers. Klinghoffer replaced his friend and frequent collaborator John Frusciante, who left the band in 2009. Klinghoffer was inducted into the Rock and Roll Hall of Fame with the Red Hot Chili Peppers on April 14, 2012, becoming the Hall of Fame's youngest-ever inductee.

Klinghoffer also fronts Dot Hacker, and was a member of Ataxia (alongside Frusciante), The Bicycle Thief and Warpaint. He most commonly plays guitar or drums, and sings backup as well as lead. He has also both recorded and toured as a session musician with Gnarls Barkley, Sparks, PJ Harvey, Beck, The Butthole Surfers, Golden Shoulders and Vincent Gallo amongst others.

Dropping out of formal education at age of 15, Klinghoffer became involved in performing and recording music in Los Angeles at an early age. Klinghoffer describes himself at this time as "[the] little music dork who lived around the corner, dropped out of high school, and was just playing guitar all day long." In 1997, at the age of seventeen, Klinghoffer joined The Bicycle Thief, the then-current project from former Thelonious Monster frontman Bob Forrest. Red Hot Chili Peppers vocalist Anthony Kiedis noted that, "Bob [Forrest] has always had a very keen sensibility about finding extremely talented and down-to-earth people who just want to get to a kitchen and write a song." The band's subsequent studio album, You Come and Go Like a Pop Song, marked Klinghoffer's first recording experience. Regarding bandmate Forrest's notorious drug addiction, which arguably stalled Thelonious Monster's commercial success, Klinghoffer stated at this time that he: "Pretty much had enough confidence in myself to know that I wasn't gonna be 'the next Bob Forrest'."

Anthony Kiedis (/ˈkiːdɪs/ KEE-diss; born November 1, 1962) is an American vocalist/lyricist, and occasional actor best known as the lead vocalist of the Grammy-winning band Red Hot Chili Peppers. As an actor, he has appeared in F.I.S.T, Point Break, and The Chase. Kiedis published an autobiography entitled Scar Tissue in 2004.

Kiedis spent his youth in Grand Rapids, Michigan with his mother before moving, shortly before his twelfth birthday, to Hollywood to live with his father. While attending Fairfax High School, Kiedis developed close friendships with fellow students Flea and Hillel Slovak, who at the time were members of a band called Anthym. After high school, Kiedis began taking classes at UCLA, but dropped out during the beginning of his sophomore year. He later received an offer to be the opening act for a local band, and enlisted Flea, Slovak, and drummer Jack Irons to assist. After a show under the name "Tony Flow and the Miraculous Masters of Mayhem", the band progressed and the line-up eventually became the Red Hot Chili Peppers.
