Tortoise: Beacons Of Ancestorship

When Tortoise’s It’s All Around You arrived in 2004, some critics suggested that the band was at a creative impasse: John McEntire and his virtuosic post-rock warrior brethren had honed their songs to the point of becoming background music, that great graveyard of well-intentioned instrumentals. Around was clean and tight, whereas young bucks like Battles were starting to experiment with a mathier, full-tilt version of the Tortoise sound. Well, if Beacons Of Ancestorship isn’t counterfire, then nothing is. The album can be roughly split down the middle, with an emphasis on rhythm up front. The opener, “High Class Slim Came Floatin’ In,” is distinguished by its blurting funk synth and low-lying Madlibbian groove, while “Northern Something” verges on dubstep with its metallic percussive bits and bizarre bass sounds flitting atop a carnaval two-step. “Gigantes” is a minimal, micro-chopped polyrhythmic feast; “Penumbra” jerks forth on a sampler beat; and the monstrous “Yinxianghechengqi” features punk drumming, sharp jags of guitar distortion, and blown-out bass.
