Poly Chain is the brainchild of Kyiv-born Sasha Zakrevska, who follows up her Fairy Disco LP from last year with this six-strong EP of cold and calculating electro workouts for Mechatronica. The likes of 'IRIS-T' favour a breakneck pace and the kind of steely sound design which aligns with DJ Stingray's approach as a DJ and producer. On the B side, 'Tryton' and 'ATACMS' play around with some more fluid synth shapes, but the mood remains tough and edgy throughout this knockout release from a sharp-rising talent in the electro field.
