One of the coolest (literally; it may still be a bit nippy outside) downtown Spokane music venues opens up Friday as the publicly funded KYRS radio station kicks off its summer concert series on the glorious Saranac rooftop. With Spokane/Coeur d’Alene blackened hardcore acts East Sherman, Phjior and Déformer playing up a storm, the music is sure to raise a few eyebrows from passersby below. Each band plays perilously loud and fast, conjuring up a raging sound that reverberates through your rib cage and skull. This isn’t some garden party; instead, expect to rock hard into the night, and perhaps plan on bringing the earplugs.
