Paul Mac is one of the UK's real techno veterans, a producer with a sizeable back catalogue spanning a variety of sounds. For this EP, a taster for an album of the same name, he focuses on deep, Detroit techno, but with a twist. The title track is a driving affair, but Mac lends it a musical sound with evocative, breezy chords combined with dramatic string stabs. "Undoubted" sees him go down a more tracky route and its heads-down groove veers close to militaristic, but he keeps it on the right side thank to the clanging drums and crashing percussion. Marcel Fengler also contributes an excellent, wobbly bass-led version of "Insomnia".
