The Freak Scene was never a "group" in the sense that the Beatles, the Rolling Stones, or the Byrds were a group -- that is, they didn't really function as a group or play as one. In fact, they had slightly more in common with the Monkees or, more correctly, perhaps the original Grass Roots, in the sense that the Freak Scene was whatever its producer-songwriter had in mind.
The Freak Scene was a studio-created ensemble, the brainchild of Rusty Evans, a one-time Greenwich Village folkie turned producer. Evans had crossed paths with Bob Dylan and Felix Pappalardi early in his career, before they went their separate ways, and he ultimately became a producer and dreamed up the Freak Scene as a project. David Bromberg was the first musician tapped for the "group," a sort of in-house psychedelic band created to record one album, Psychedelic Psoul. The one album to their credit is a period piece, an effort at making topical psychedelic music at a time when Columbia had nobody (other than the Byrds and, in his own way, Dylan) who was really good at making those sounds.
