Chicago DJ and producer Olin follows up the debut release on his new record label, Boundary Movement, with TPI featuring four diverse cuts. Up-tempo electro, moody minimalism, old-school melodies, and chugging deep house all woven seamlessly. The A side begins with “TPI,” an exercise in minimalism and micro-detail. Unmistakably Olin’s own, insistent synth stabs keep time while needlepoint percussion keeps the ear guessing. If you thought Olin’s palette was limited to techno and house, A2 “Corsaren” will prove you wrong — this is pitch-perfect electro in a classic style, a slow-building interplay of sci-fi synthesizers wrapped around icy cool call-and-response kicks and handclaps. B1 “Thanks Rob” is BOM02’s most straightforward cut — and one of its best. Building momentum slowly across its eight-minute runtime, “Thanks Rob” impresses as the larger-than-life bass swell hits. The dancefloor will be rapt – proceed carefully. B2 “Hyssop,” feeling like it comes from a similar vintage as “Corsaren,” might have been called “ambient techno” decades ago, but its upwardly mobile percussion makes it feel as at home in a club as it does in the chill-out room. It’s just the thing to close out this broad-spectrum record. – Chris Zaldua
