Two stalwart scuzz/street punk acts will romp through San Anto this weekend to satisfy your urge for the kind of off-the-grid, socially antagonistic catharsis that only the purest of throwback punk acts can muster. Orange County-bred Total Chaos, for starters, is a hardcore punk band that’s been at it since 1989. Fronted by SOS Records co-owner Rob Chaos, Total Chaos is a band with a unique appreciation for activism within the punk community, especially in Cali, and its sound reflects that desire to honor the sonic and ideological roots of the genre. U.S. Bombs, meanwhile, formed in the early 1990s in Pomona, California, and makes a brand of street punk that hearkens back to the LA and NYC punk scenes of the late 1970s. The band released one of its strongest albums yet, Road Case, at the end of last year, a testament to the its staying power.
