Then there's Crimson Wave's scant but compelling recorded output. On its self-titled demo from 2013 there is a rarefied kind of DGAF-but-really-GAF spirit when it lets songs wander ('Down') and stumble around like some surf-rock 45 played at 33 RPMs ('Lay Me Down'). Then last year, it straight-up mastered plucky controlled chaos on the single 'Say'/'Calling You.' Go back to that demo though and check out 'My Lap,' in which a pop-punk riff gets engulfed by My Bloody Valentine and This Heat atmospherics, capturing a particularly stoic, bittersweet, and striving sadness. It's my favorite CW song, for what it's worth, and it kind of sounds like what it feels like when a cool, small band comes to an end. And finally, as far as I can tell, the City Paper got through years of covering Crimson Wave without ever making a period joke? That's really something for us. 8 p.m. Metro Gallery, 1700 N.
