Since its mid-90s heyday, trip hop has been represented only on a sporadic basis. A shame because when it's good, it's still a healthy genre which, at its best, can be moody, menacing and often moving. Psyrok are unlikely to revolutionise the fortunes of trip-hop but they are a reminder of better times. 'The Difference' is a fine start as smoky effects, sampled dialogue, whispered vocals and dark keys set up their noirish agenda. 'Soma' steps up the pace a notch and its chugging rhythm works best of all these tracks. The experimental 'I'm Threw' and 'Viable Commodity' are rather less edifying but 'Fly Dub' is a stark improvement with reggae vocals and canny use of echo. By no means perfect, Psyrok provide a solid set of songs and grooves for those who crave a post-midnight listen.
