Flea's stepfather, Walter Abdul Urban (1941–2011), frequently invited musicians to his house, where jam sessions would often take place. The family moved again to Los Angeles, California, where Flea became fascinated with his trumpet.[7][8] He had no interest in rock music at the time; he idolized jazz musicians like Miles Davis, Louis Armstrong and Dizzy Gillespie.[7] His stepfather was an "aggressive alcoholic", who eventually became involved in shoot-outs with police. "I was raised in a very violent, alcoholic household", Flea later said, "I grew up being terrified of my parents, particularly my father figures. It caused [me] a lot of trouble later in life."[9] To cope, Flea began smoking cannabis at 13, and became a daily user.[10]
