Debuting last April, Sonoma County punk rock promoter Shock City, USA excels at ushering in nationally and internationally touring bands to Santa Rosa. This month, Shock City welcomes Barcelona post-punk band Belgrado, currently touring in support of their excellent new record, Obraz. Belgrado combines vintage bass and drum riffs, à la Joy Division, with the ethereal vocals of lead singer Patrycja Proniewska for a cool sound that’s straight out of 1979. Supporting Belgrado is Chain of Flowers, hailing from the U.K. and boasting densely packed punk and sublime shoegaze songwriting. Oakland’s melodic punks Silent Era and Sonoma County rockers Service fill out the bill on Monday, Aug. 15, at the Beach Warehouse, Santa Rosa. 7pm. $10. Email [email protected] for address.
