Throbs (1972)

Coming in the wake of a whole movement of wild, ecstatic, psychedelic films loaded with unchecked energy and abandon, Throbs demonstrates a remarkable subtlety and restraint, as Fred explores variations in loops and cycles, weaving unlikely combinations of found and original footage to envelop us in a free associative dream world. —Mark Toscano.
