Fronted by former Psychic Hearts vocalist/guitarist Matthew Rain, Athens' trio TWIN TIGERS meld the darkest parts of the psychedelic '60s with moody, post-goth, pop and indie-rock intonations. Locals Abby Go Go draw from a similar well of influences, but focus their efforts on crafting long, sustained bouts of hypnotic rhythm and resonance. Think Stereolab, the Jesus & Mary Chain, and a dose of methadone and you're at the right party. The Louder than Dreams DJs spin records afterward. $7. 10 p.m. 529, 529 Flat Shoals Ave. 404-228-6769. www.529atl.com.
