The band began in 1969 in Boulder, Colorado at the University of Colorado with Kris Moe as the keyboardist, Linn Phillips on guitar, Warren Knight on bass, Harold Fielden on drums, and Mick "Flash" Manresa also  on guitar and as the group's front man. The band got its name, "Flash Cadillac & the Continental Kids" from Hughey Plumley who spent most of his time in the back of a Boulder bar, The Sink, and who entertained himself by creating names for bands. Moe and Phillips' brother, Linn, were college roommates. Through that connection, Moe and Phillips formed the band and played their first performance in February 1969 at a frathouse party. The group moved to Los Angeles in 1970 to try to break into the music scene there. When "Flash", the original lead singer, along with  several other band members decided to return to school in 1971, Moe, Phillips, and Knight decided to replace "Flash" by holding auditions.
