Two recent episodes of "Radio Theatre." First: "Enthusiasm! The Dombass Symphony" (1930) by Dziga Vertov, a symphony of abstract industrial noise for which a specially designed giant mobile recording system was constructed (it weighed over a ton) in order to capture the din of mines, furnaces and factories. Then: "In 1966, then General Manager for KPFK Los Angeles 90.7fm Paul V. Dallas decided to turn to the 24 hour fundraising Marathon technique to raise money for the stations operating expenses. Here is a 5 minute clip from September 13 1966 of a young Pre-Firesign Theatre Peter Bergman and Paul Robbins as they hosted phone calls in their own unique counter-culture way during KPFK's first Marathon fundrive. In the second clip then General Manager Paul V. Dallas speaks to the audience about the program Radio Free Oz after it's first 8 weeks on the air. KPFK was hit with a barrage of letters in support and against this Free Form Radio experiment hosted by Peter Bergman and Paul Robbins. Also included in this show is Dymaxion's "Chase Scene/Transistor Radio," John Ashberry's "Rivers and Mountains" from 1963, and Venus Flytrap from "WKRP in Cincinatti" explaining the atom."
