From Wikipedia

Michael Peter Balzary (born October 16, 1962), more commonly known by the stage name Flea, is an Australian-born American-raised bassist and occasional actor. He is best known as the bassist and co-founding member of the alternative rock band Red Hot Chili Peppers. His work with the band incorporates several musical styles, ranging from aggressive slap bass to more subdued and melodic techniques. Aside from the Red Hot Chili Peppers, he has collaborated with many artists, including Jane's Addiction, Thom Yorke, The Mars Volta, Alanis Morissette, Ziggy Marley, Slash, Damon Albarn and Bryan Ferry.

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 joined the group, but quit several months later in order to play for the punk rock outfit Fear. He soon rejoined Slovak to form an intended one-off band along with fellow high school alumni Anthony Kiedis and Jack Irons; the impromptu collaboration would ultimately give birth to the Red Hot Chili Peppers.

Flea has made numerous forays into acting, appearing in films that span many genres such as Back to the Future Part II (1989), My Own Private Idaho (1991), and The Big Lebowski (1998).

Flea is credited on the following Roxy Music and Solo Albums
