Electric Collage was the first Light Show in Atlanta. It began as experiments with light and color for The Catacombs. When a member asked David Braden if they could get things and do a light show at The Catacombs, he reportedly replied, “Go ahead, do it! Why are you asking me? I’m NOT your mother!” Thus he began to be called Mother David.
From that they grew.
Steve Cheatham and Frank Hughes have a wonderful site on the later Electric Collage.
