This video documentary by Don McGlynn (The Howlin’ Wolf Story, Charles Mingus: Triumph of the Underdog) profiles Minneapolis folk musician Spider John Koerner, one of the earliest proponents of the folk-blues revival. Performing with musicians Dave Ray and Tony Glover, Koerner helped inspire interest in the work of America’s neglected blues pioneers. But in the early 70s he suddenly quit playing the blues, saying “I didn’t want to try to be a black guy anymore.” Mixing extensive live footage and interviews with Ray—who died during production—and Glover, McGlynn crafts a sincere if rather dry portrait of Koerner, an individual far more interested in what he calls the “folk process” than the music biz. 98 min.
