Hot Summer Nights: Riverboat Gamblers, Sealion, Dentist, Hey Jellie, the Sour Notes

Austin’s premier punk detonators, Riverboat Gamblers unleash furious, Detroit-style proto-punk on Austin only rarely now, spin-offs Drakulas and Broken Gold appearing more active. Time to rattle bones again! Dallas’ Sealion rip out a reverb-drenched surf/psych hybrid. Archetypal indie rockers, the Sour Notes’ new covers LP, This Is Not Our Music, finds them essaying songs from the Ronettes to Sleater-Kinney. – Tim Stegall
