Beacons of Ancestorship is Tortoise's sixth album, originally released in 2009. This re-issue is pressed on high quality virgin vinyl and presented in an old-style tip-on gatefold jacket with art worked inner sleeve and free download card. A characteristic Tortoise album is one that traverses an encyclopedia of styles and reference points, a document of where musical intersections and dialogue are occurring at a given moment in time. Beacons of Ancestorship is no different, with nods to techno, punk, electro, lo-fi noise, cut-up beats, heavily processed synths, and mournful, elegiac dirges. We see these ideas working out in compositions like High Class Slim Came Floatin In, an eight-minute track which playfully references the world of ecstatic rave and dance culture with a curiously ambivalent, multi-part suite overlaid with robotic, machine-sounding melodies that stop and start in several different time signatures before the song's ultimate resolution; and again in Yinxianghechengqi, which begins as a straightforward up tempo math-rocker before steadily accelerating into a wall of fuzzy atonal sqwonk.
