From the vaults of the popular psychedelic show ‘The Radio Lab’ which later became ‘Cryptic Propensity Projections’ and ‘Midnight Collage’ on KBOO FM, Portland, Oregon from 1971-1985, Michael Christopher, Harry Mishkin and Bill Reinhardt talk to Frank Zappa after his performance at the Paramount Theater in Portland, Oregon. In the first clip, Frank discusses Germans, pop culture, the music scene and his own dubious popularity. In the second clip, he discusses musical interests, critics, and former ‘Mothers’ drummer, Jimmy Carl Black. The third clip is a spicy stew of The Mothers of Invention and The Firesign Theater. Unavailable since it’s broadcast on the Radio Lab in 1974.
