Angel was discovered by Kiss bass player Gene Simmons performing at a nightclub and was eventually signed to the same label as Kiss, Casablanca.

Angel's image of dressing in all white was a deliberate contrast to Kiss, which wore black. Angel sported an androgynous image and elaborate stage sets. They were slammed by rock critics, and Frank Zappa ridiculed the all-male band’s feminine appearance in the song "Punky's Whips". Angel never achieved mass commercial success but acquired a following as a cult band.
