Bay Area drummer and composer Weasel Walter once described Barr's axmanship as a "fractal-like inner logic that is both chaotically asymmetrical and perfectly ordered at once." This is a dramatic critique because Western minds traditionally view order 'n' chaos as an either/or proposition, but Walter is right. After cranking Shred Earthship for several hours, I have no idea whether Barr and Hill are manic, free jazz-inspired improvisers or the world's most detail-oriented progressive composers, as their screaming duets microscopic clusters, explosions, and violently sputtering orgasms full of hyper-pinprick note play and rapid-fire grooves feel both fluid and crystalline. And regardless of a track's duration, which varies here from 20-second, Napalm Death-type blasts to nine-minute epics, I'm always left with this same damn remarkable impression. The probing abstract metal from this tenacious pair has proven that a minuscule number of minds in our 21st-century society have definitely advanced beyond such a juvenile dichotomy as form or formlessness.
