Freak by Carmen D’Avino

Carmen D’Avino was one of the leading figures in the avant-garde film movement of the 1950s, 1960s and 1970s and was a pioneer in animated short films. This short was shown on the Electric Company in the 1970s. Its imagery and sound has stuck with me ever since I first saw/heard it. I can not find a reliable source for the music, but some have speculated that it is Lenny Popkin.
