There are moments on Sea When Absent, the new album by A Sunny Day in Glasgow, that may actually give you a head rush—in part because of the hyperchromatic, pitch-shifty production by Jeff Zeigler, but mostly because the Philly-formed collective writes noisy, sugarache pop songs that seem to be constantly unmaking and remaking themselves. When the first chorus hits in “Oh, I’m a Wrecker (What to Say to Crazy People),” you’ll twist your headphone jack for fear you lost a channel, but quickly realize that it’s a feint, some misdirection before the song blossoms into a full-on anthem. Their M.O. is confusion, then catharsis—usually abetted by rainshowers of beat-up-sounding synths, heaven-scratching fuzz, and singer Jen Goya’s cut-up rounds and aching melodies. Sea When Absent isn’t A Sunny Day’s most ambitious record—hat-tip, 2009’s Ashes Grammar—but it feels like the band’s most fully formed, mining both its early experiments in cacophonous pop and the more immediate, less produced songwriting of the 2010 self-released album Autumn, Again. If you stumble for a moment tonight, just brace: The band’s next move will be lifting you back up. A Sunny Day in Glasgow performs with Cigarette at 9 p.m. at DC9, 1940 9th St. NW. $10.
