Per Mutations has eight members listed. I'm not sure if that's all at once but their sound is diverse enough that I might think so. Surfing in the Phenomenal World has moments of reverby surfy-ness, but less than they suggest, with flashes of shoegaze, spaghetti western, maybe even some Tom Waits... all the while sounding pretty fun and cohesive. Reminds me a bit of The Tomorrowmen's Futourism in its non-pretentious adventurousness. A pleasant surprise and over way too soon.
