Producer Hans Thalau reinvigorates his long-running colours series, this latest instalment — the first since 2013 and the first of four new shades — being 'black'. 'AA' is a languid introduction, robust house music at the 95bpm mark. It soon gives way to 'BB', a rattling, arpeggiating, trance-inducing excursion. 'CC' is considerably firmer, Fred P-style pads warming every inch of you. Winding up with 'DD', more pads and strings envelop you like a warm but slightly unsettling dressing gown. Long may the colours flow.
