The MOUNTAIN GOATS' principle songwriter, singer/guitarist John Darnielle, has come a long way since his days of cranking out homemade and willfully obscure lo-fi cassettes. The ramshackle and Muppet-voiced troubadour has leveled off a bit and upped the indie/folkie ante with his 4AD releases of recent years. Darnielle and Co. play songs from their latest biblically themed offering, The Life of the World to Come. Georgia native turned New Yorker Larkin Grimm plays a rare local show of her spectral, avant-garde folk numbers that are at once sinister, angelic and uncomfortably alluring. Canadian composer/violinist Owen Pallett, aka Final Fantasy, also performs. $17.50. 9 p.m. Variety Playhouse, 1099 Euclid Ave. 404-524-7354. www.variety-playhouse.com.
