Book of Genesis illustrated is probably the most inspired and insightful biblical interpretation in the last thousand years. You can in fact be smart and crazy. It may even be easier to be creative and crazy. But I didn't come here to give my armchair diagnosis of Americas favorite savant comic book artist. I came here to write about R. Crumb and radio.
People that know Crumb, or even know of Crumb, usually know that he is a fan of dusty discs almost on par with Joe Bussard. Crumb has recorded his own albums and even a couple 78 rpm singles in the early 1970s. The Cheap Suit Serenaders are an old time string band mostly doing covers of song from the 1920s. It's strangely wholesome. When he relocated to France, he started a new band Les Primitives du Futur. But that was it so far as I know. He was a music geek, not a radio geek. He's always avoided discussing his work with the media and was very distant even in his own documentary footage. His discomfort is apparent.
Jerry Zolten produced a one-hour one-shot program on 91.5 WPSU. Crumb could have probably picked any non-com in America.. and he picked a 1,700 watt college station in State College PA. It's market # 249 of a possible 290. Even with the stations 3 repeaters: 102.5 W273BE Huntingdon, 104.7 W284AK Clearfield, and 106.7 W294AE Altoona... it's still one of the smallest and least dense markets he could possibly have selected. The show was called "Chimpin' the Blues" and they spent it spinning old blues and gospel and discussing the various oddities and gems in Crumb's personal 78 collection. The program is archived online at prx.org. It is very much worth listening to.
He also hosted a half hour, four-part radio series on BBC Radio 3 as part of the Jazz File program. (one source says it had 5 parts) The Jazz File runs for half an hour on Saturday nights at 5:00 PM. BBC 3 mostly airs Opera and Classical so the program is a "specialty program" in the western sense. Crumb spun 78s from his own collection focusing on the 1920s and 1930s primarily. I cant find an exact date but it appears to have run in 2001 or 2002.
