Trivia

Rode in the ambulance with River Phoenix the night he died.

His first instruments were the drums, then the trumpet, and he didn't play a bass guitar until the age of 17 when his friend, Hillel Slovak, asked him to join his band Anthym and helped him learning how to play the bass. However his step-father was a jazz bass and upright bass player.

He and Kurt Cobain (as well as other members of Nirvana) were bound by a friendly relationship since the Red Hot Chili Peppers and Nirvana had been touring together in the early 1990s. He even played the trumpet on "Smells Like Teen Spirit" at one of their shows.

Was close friends with actor River Phoenix. As well as co-starring with him in My Own Private Idaho (1991), he also occasionally played and recorded with Phoenix's band, Alekas Attic. One of the band's released tracks, 'Note To A Friend', features Flea on bass.

Anthony Kiedis, Hillel Slovak, Jack Irons and him formed a band called Tony Flow and the Miraculously Majestic Masters of Mayhem (later to become the Red Hot Chili Peppers).

Co-founder of the Silverlake Conservatory of Music, a music school located in a rough, artsy neighborhood in Los Angeles.

Met Peppers pal Anthony Kiedis at Fairfax High School.

When a kid, he played the trumpet and wanted to become a jazz trumpet player.

Firm supporter of art conservatory schools. As stated in a radio interview, he reached out to the public to donate money to these schools due to budget cuts.

Played bass on the album "De-Loused in the Comatorium" by the Mars Volta.

The nickname Flea comes from a joke he had with some of his high school friends. At some point they decided to call each other with a cartoon name, and finally "Flea" remained as the name by which all of his friends were calling him. His friend from junior high, Keith Barry, who played saxophone with the Red Hot Chili Peppers during the Mother's Milk tour in 1989-1990, also got his nickname "Tree" the same way.
