Portland rock quartet the Rotties have been tearing up the Northwest for over four years. In that time, they've developed a fierce sound that's landed them spots on plenty of hardcore-punk-leaning bills. It's a good fit—the band's in-your-face intensity, driven by dueling vocals and headbang-inducing metal riffs, has the ability to topple just about any audience. What makes them stand out in this aggressive arena is the attitude with which they unleash all this energy. At the end of the day, the Rotties want to party with you, and they're willing to use every tool in the punk-rock playbook to get the job done. CHIPP TERWILLIGER
