Local dobro legend Mike Auldridge comes from a musical pedigree of the first order. His uncle, Ellsworth Cozzens, was a member of a ’20s-era Washington string band, the Blue and Gray Troubaudors, and accompanied Jimmie Rodgers on his first Camden sessions in 1926. Auldridge learned to play from his uncle—who was one of the earliest practitioners of the steel guitar—but it wasn’t until he heard Josh Graves that he got hooked on the dobro. A founding member of the Seldom Scene, Auldridge helped make D.C. the bluegrass capital of the world in the ’70s. These days, Auldridge stays busy with a slew of projects, including the recent Tone Poems III, with mandolin wizard David Grisman. His current local band, Auldridge-Bennett-Gaudreau, has an upcoming release on Rebel, Blue Lonesone Wind, that is a bracing relief from the doldrums of pick-by-the-numbers contemporary bluegrass. The show begins at 8: 30 p.m. at the Outta the Way Cafe, 17503 Redland Road, Derwood. $10. (301) 963-6895. (Eddie Dean)
