First released in the US last spring, 936 is the UK debut by Peaking Lights – a romantic and musical partnership in which tattoos and long hair feature prominently. None of this really prepares you for their sheer uncategorisability. You could call this a dub record, but it's not reggae – more a pulsating fusion of burbling analogue synthesisers and ancient psychedelia occasionally topped off by the echoey vocals of Indra Dunis, a kind of lost, mellow American member of the Slits. Dunis's flat tones can let the side down, but otherwise, the swoon is in the details, like the faux-harp wobble on "Synthy" that recalls Alice Coltrane.
