The best way of bringing together Steve Summers’ raw, analogue techno and the esoteric electronic drone of Exoteric Continent is to put Zero in the middle to DJ. Between them, the American, with releases on LIES, Clone and his own Confused House label, and the man from Barcelona, with LPs like Opal Tapes and Hospital Productions, cover such a wide spectrum that they should more than satisfy any fan of underground electronica, particularly live performances. With Zero completing the task, tonight becomes an event no-one who knows anything about the subject ought to miss.
