Detroit and Berlin have long been connected through techno. With D1aspora, a sublabel of Ireland’s D1 (distributed by Submerge), Dublin asserts its own sister-city relationship with the D. Scott Logan’s four tracks offer a subtle, melodic take on Motor City techno with plenty of punch. “Cigling” and “Gronk” are classic exercises in syncopated machine rhythms and gentle squeal, while “One Chord” and “Lia Fail” explore resonant sub-bass and minimalist clatter.
