Known as “the Cajun Hank Williams,” Erath, La., guitarist D.L. Menard topped the country charts in 1960 with a song that has since become a bayou standard, “The Back Door.” Though his high-pitched, nasal vocals and rhythmically deft strumming never again made it to the Top 10, this part-time furniture maker and 1994 NEA National Heritage Fellowship award recipient has continued to tour and record. Expect straightforward rural dance sounds with Menard’s twanging axwork and mostly French storytelling lyrics augmented by the accordion and fiddle players who make up his band, The Louisiana Aces. A beginner’s Cajun dance workshop starts at 8 p.m. and the music at 9 p.m. at Glen Echo Park’s Spanish Ballroom, 7300 MacArthur Blvd., Glen Echo. $10. (Menard will return on April 20 to Cherry Hill Park, 9800 Cherry Hill Rd., College Park). (301) 309-0895. (Steve Kiviat)
