Biafra is an ardent collector of unusual vinyl records of all kinds, from 1950s and 1960s ethno-pop recordings by the likes of Les Baxter and Esquivel to vanity pressings that have circulated regionally, to German crooner Heino (for whom he would later participate in the documentary "Heino: Made In Germany"); he cites his always growing collection as one of his biggest musical influences. In 1993 he gave an interview to RE/Search Publications for their second "Incredibly Strange Music" book focusing primarily on these records, and later participated in a two-part episode of Fuse TV's program "Crate Diggers" on the same subject. His interest in such recordings, often categorized as outsider music, led to his discovery of the prolific (and schizophrenic) singer/songwriter/artist Wesley Willis, whom he signed to Alternative Tentacles in 1994, preceding Willis' major label deal with American Recordings. His collection grew so large that on October 1, 2005, Biafra donated a portion of his collection to an annual yard sale co-promoted by Alternative Tentacles and held at their warehouse in Emeryville, California.
