Crumb director Terry Zwigoff's first film is a true treat: a documentary about the obscure country-blues musician and idiosyncratic visual artist Howard "Louie Bluie" Armstrong, member of the last known black string band in America. As beguiling a raconteur as he is a performer, Louie makes for a wildly entertaining subject, and Zwigoff honors him with an unsentimental but affectionate tribute.
