MOGWAI hits up the Variety Playhouse in support of its latest full-length, The Hawk Is Howling. The Scottish quintet is well-known for its formulaic post-rock approach to songcrafting, which often includes lengthy instrumentals and a low dose of vocals – best not muddy the musical waters. Fuck Buttons open. $18-$20. 8:30 p.m. Variety Playhouse, 1099 Euclid Ave. 404-524-7354. www.variety-playhouse.com.
