Shellshag are known for four things: a relentless tour schedule; a stalwart DIY attitude; jumping on people, throwing their drums, crowdsurfing, and other mischief; and making more fuzzed-out, Breeders-like noise than two people should be able to. Akimbo are known for two things: grinding, fast, melodic metal and the best drummer in Seattle. Helms Alee are known for one thing: stoned freak-outs of the heavy, slow variety.
