Yorkshire's underground has always run deep and this double pack from one of the region's finest new labels, Hearlucinate, makes the case well. For this double album, Leeds mainstay Tristan da Cunha has done a careful excavation of Scott Featherstone's DAT archive featuring music recorded under his Triform alias entirely on analogue hardware. The results are simultaneously timeless and urgently present, and the kind of machine jams that only reveal their full power in dark, hazy rooms. 'Harmony' has a dark and sleazy soul, there's muscular drum weight to 'What Is This', 'Basic House Rocker' has an anxiety-riddled sound that's alive with twitchy acid electronics and 'Chimes' marries vast, swinging kicks with Detroit soul. Wonderful.
