Alex G has put out a handful of EP's and five full-lengths since 2010. The band's most recent project, "DSU" (2014), is lo-fi and emo, and as curious as it is captivating. These guys noodle a few genres. Guitars jangle dissonant while vocals float delicate, and keys add clear contrast to distorted strums and searching melodies. Next month they head to Europe for a string of shows before continuing their US tour. Also on the bill is Teen Suicide, Skirts, Alleys and Drive Me Home, Please.

Alex G plays Wednesday, January 28, at the Bug Jar, 219 Monroe Avenue. 8:45 p.m. $10-$14. bugjar.com; sandy.bandcamp.com.
