One can only wonder what’s in Oakland’s water system. But whatever it is, Deerhoof, Da Hawnay Troof, and Experimental Dental School are all guzzling the same stuff, and it’s twisting their musical minds in similarly demented ways. Experimental Dental School is an exercise in fractured discord, with a spectacularly blatant disregard for tempo or melody. The band is beholden to no musical convention, abusing their guitars, organs, and drum kits into a sound that veers between noise-, math-, and art rock. As their name implies, experimentalism rules supreme, with ragged chord progressions and clamorous drum sequences reining themselves in just as they begin to blow minds–and thankfully before they blow eardrums.
