The Blind Boys of Alabama: Spirit in the Dark featuring Yo La Tengo, Yim Yames, Lambchop, Marshall Allen and the Sun Ra Horns and Exene Cervenka

Formed in 1939 at the Alabama Institute for the Negro Blind, the Blind Boys of Alabama have in recent years covered Funkadelic and the Rolling Stones, recorded a freaky album with pedal-steel prodigy Robert Randolph, and shared bills with Prince (at a club) and Dylan (at the White House). This week, the group—by now whittled down to just one original member, Jimmy Carter—spearheads its own three-night festival. Tonight is indie-rock night, as the Blind Boys welcome appearances from Yo La Tengo, My Morning Jacket singer Yim Yames, Nashville country-soul outfit Lambchop, X's Exene Cervenka, and one non-Pitchfork-ish group, Marshall Allen and the Sun Ra Horns.
