Operation Barbarossa was the code name for the German invasion of the Soviet Union during World War II. While I don't think that this particular Rochester-based quartet has a penchant for the Third Reich, the name is fitting: the group's sound is powerfully intrusive in the best possible way. Its moments of ambient expanse and cinematic post-rock are balanced by a sharp, yet almost indiscernible edge. Imagine a rose garden surrounded by a barbed-wire fence — as gorgeous as it is menacing.
Barbarossa performs with White Woods, We've All Drowned Once, Strawberry Girls, and Stolas Sunday, September 1, 5-9 p.m. at Dub Land Underground, 315 Alexander St. $10. facebook.com/dublandunderground
