Ernest Berk! I really thought he had to be one of those made-up "outsider electronics" composers a la D.D. Denham and Ursula Bogner (earnest berk, get it?). But no he seems to be, or have been, real, judging by this soundtrack to a BFI film by David Gladwell from 1964. Supposedly Berk was a a German naturist who ran a dance commune in 1960s England. Or says the dude from Public Information, who is putting out a FC Judd-style anthology at some point.
