Despite frequent lineup changes and the shuttering of nearly every club in Boston where the band played early on, shoegaze act Swirlies has reached its 25th anniversary. From its dream-pop roots on the 1994 EP Brokedick Car to the heavier sounds of 1998’s Strictly East Coast, Swirlies has been able to not only keep the attention of fans old and new, but evolve their sound. While the band started out with a more mellow, lo-fi guitar drive, its members’ latest offerings, as part of spin-off groups like the Yes Girls, possess a little more electricity. To celebrate this quarter-life milestone, the band reissued its 1993 album Blonder Tongue Audio Baton and will tour the country playing the album in its entirety. It’s fitting that Blonder gets the spotlight for Swirlies’ milestone. It encompasses the band’s best looks: sometimes sleepy and beachy, always lo-fi and dream-like. Swirlies performs with Big Hush at 7:30 p.m. at Black Cat,1811 14th St NW. $15. (202) 667-4490. blackcatdc.com.
