On their fourth album, you can totally tell this instrumental trio comes from Chicago, home to Tortoise and Sea and Cake. Russian Circles' metal machine Muzak basically rushes in circles like a louder, distorted version of the new agey so-called "post-rock" that those bands concocted back in the '90s. There's plenty of bloodily valentined oceanic shoegaze, too, which aligns them with combos like Isis, Pelican, Cult Of Luna and Red Sparowes. In "Atackla," they even manage some bombastic Glen Branca overtones. And in closer "Praise Be Man," they finally murmur a few words.
