Their new record won't be out until May, so to get their fix, Russian Circles fans must listen to the 2006 debut, Enter, for the thousandth time. Enter is a spooky collection of dynamic instrumentals—haunting guitars, explosive drumming, and moments of brightness fighting their way through otherwise solemn structures. It's great, but I long for the new record. Tonight will whet the appetite: Their live show is more epic than a studio could ever capture. With Red Sparowes.
