Quartz is a respected drum & bass head with a precise and minimalist - but always cinematic - production style and that's clear again on this new one for Droogs. The A-side features solo cut 'Duplicity', which is a stark and electrifying trip into drum & bass darkness with tight basslines and subtle shifts that prove less is more. The B-side, 'Black Prism,' sees Quartz team up with Overlook for a throwback to raw 90s techstep and all the tight but manic breakbeat action that comes with it. It's a tune of unrelenting tension that resolves into an unexpectedly serene close. Sophisticated stuff from all.[info sheet from distr.]
