Cromagnon was an obscure psychedelic rock/avant garde collective, and the subject of much speculation among fans. Many rumours about the band have come and gone over the years. It is only known that they were comprised of pop songwriters Austin Grasmere and Brian Elliot, who claim to have written a string of pop hits before the band, although this claim seems to be questionable. The mysterious "Connecticut Tribe" was called in to help with the project, and Orgasm was released on the ESP-Disk label. It was re-released as Cave Rock later on ZYX Music.
