Southern Indiana's pre-eminent purveyor of blues, stomp, and vintage country freakout, The Reverend Peyton's Big Damn Band sounds like it predates FM radio. The Reverend Peyton's booming yet inflected voice and his finger-picking guitar style are the keys. Both lend rootsy qualities to the tunes while his band — which isn't big — creates an authentic backbone. It's a guitar, washboard, and drums trio that parties like its 1939. The Reverend Peyton's Big Damn Band will also make a free in-store appearance at The Record Archive, 33 1/3 Rockwood Street, on Thursday, May 3, at 6 p.m.
