Young’uns, listen up. Before Twitter, there was Bob Fass, the night FM disc jockey that revolutionized what radio could be, what it could do for the people, and what it would mean for a cultural revolution. Fass begat free-from Radio Unnameable in 1963 on indie WBAI from New York, molding it into a potnet mix of interviews, music, absolute free speech, citizen journalism mobilization… Paul Krassner, Abbie Hoffman, Bob Dylan, Patti Smith and an endless slew of other useful hippies, icons and luminaries. In the 1960’s, ACLU called the show “a midwife at the birth of the counter culture.” I mean, this was a cool, cool dude. The doc Radio Unnameable open tomorrow for a limited run at FilmForum.
