This week's show features documentary filmmaker Rodney Ascher (Room 237) presenting an excerpt of an unreleased early film, called The Collectors. The excerpt centers on Pea Hicks, a collector of an obscure electronic instrument called the Optigan (and member of the great Optigan-driven band Optiganally Yours).     Produced by Rodney Ascher and Ross Simonini, with Jenna Weiss-Berman and Andrew Leland.
