Despite modern perceptions of Labor Day as an end-of-summer free for all, the holiday, in fact, celebrates the work of activists who fought for the rights of the working class. It’s only right, then, that we take the day to help out the local chapter of the Democratic Socialists of America to the sounds of Austin’s finest weirdo rock. On the lineup: Slomo Drags, who skewer Elon Musk fanboys with glistening synth pop (“Rich Pervert”); Batty Jr., who deliver quirky anti-folk with a Southern twang (“Cocoons”); and Big Bill, whose new LP Strawberry Seed blends punk politics (“Poverty of Wires”) with polished new genre excursions. – Carys Anderson
