After the Zombies broke up, keyboardist/songwriter Rod Argent formed his own band in 1969, which incorporated more classical, jazz, and art rock influences in accordance with Argent's musical training. The group's other members were guitarist/songwriter Russ Ballard, bassist Jim Rodford, and drummer Bob Henrit.

By 1974, Ballard had developed his songwriting talents enough to leave for a solo career, and was replaced by guitarist John Verity and string player John Grimaldi. Without Ballard, the group lost its focus and indulged its tendencies toward extended art rock passages and improvisational solos to somewhat excessive levels. Argent broke up in 1976.
