The Happy Sundays festival returns with a series of free sets that happen at various locations in the Zaferia district of Long Beach. Highlights include the evocative Latin-pop stylists Tropa Magica and indie-rock adventurers Billy Changer, as well as Rats in the Louvre, Prettiest Eyes, Janelane, The Molochs, Cat-Scan, and Birth Defects, among others. Much of the excitement occurs at Alex’s Bar, where Atlanta punk trio The Coathangers headline with the smart, provocative songs from their new album, The Devil You Know. Guitarist Julia Kugel-Montoya and drummer Stephanie Luke trade off on vocals on such subversive anthems as “F the NRA,” “Hey Buddy” and the self-lacerating “Bimbo.” Meredith Franco ties it all together with slinky, propulsive bass lines that hint at a Slits-style post-punk.

Alex’s Bar, 2913 E. Anaheim St., Long Beach; Sun., Aug. 25, 2 p.m.; free; ages 21 & over. (562) 434-8292,
