Out of Portland, Oregon, the Grails first two albums were more in the vein of post rock experimentation, then the band began to explore more psychedelic/prog passages. Thier 2007 release, Burning Off Impurities, the band travels through the desert with Middle Eastern/Arabic ambiences, almost an krautrock/acid folk texture as the acoustic guitar plays a prominent role. Hot knives and hash oil are recommended to enhance your listening enjoyment.
