On her debut solo album, Some Heavy Ocean, Los Angeles-based Emma Ruth Rundle puts away her past life as a guitarist for post-rock band Red Sparowes while creating a sound that’s also different from her current band, Marriages. Noticeably gone are the hyper-thematic instrumentals of her two previous projects; in their place are lightly layered but powerful vocals that sound equally dramatic. It seems that band life might have hindered Rundle’s creativity: From the eerie vocal loops of the title track all the way to the grunge-ballad closer, “Living With The Black Dog,” Rundle’s solo debut reveals an expansive, previously unseen range. The gloomy sounds cast a shadow over the album—at her live show, expect some darkness. Emma Ruth Rundle performs with Stephen Brodsky at 9 p.m. at DC9, 1940 9th St. NW. $10.
