LANGHORNE SLIM – born Sean Scolnick – got a helping hand from Jason Trachtenburg, who spotted him at a NYC open mic and invited the young singer/songwriter on tour with him. Scolnick emanates an impish charm and casual insouciance reminiscent of Beck, while his rootsy pop's innocent air also recalls Ben Kweller. His self-titled full-length debut is highlighted by the rollicking, organ-driven Americana, "Rebel Side of Heaven," which offers a hopeful alternative to hell, and bluesy, cabaret-tinged meditation on money and dreams with "Diamonds and Gold." $10. 9:30 p.m. Georgia Theatre, 215 N. Lumpkin St., Athens. 706-549-9918. www.georgiatheatre.com.
