Back catalogue: Dirty Dubstep/Trap/Grime

Review: To mark a century of releases, admirable Bristol imprint Tectonic has served up something rather special: an EP of future bass business that sees long-serving grime MC Riko Dan adding his flow to fresh beats from some of the label's heaviest hitters. Check, for example, the woozy "purple" synths, ragged sub-bass and stepping beats of the Joker-produced "Hard Food", the indsustrial-strength grime assault of the Pinch-produced "Vibration" and the sparse, clandestine rumble of "Hungry", where Riko Dan's gruff patois flow rises above a skeletal groove. Elsewhere, the Ziro-helmed "Alright Then" sounds like a club anthem in waiting, and Walton's remix of "Big Slug" - a previous club cut from Pinch and Mumdance - is an ethereal, string-laden treat.

Review: There was much talk ahead of the release of Darkstar's debut album as to whether the London based outfit could live up to the promise of their stunning breakthrough single "Aidy's Girl Is A Computer" on Hyperdub in 2009. The answer, in short, is yes. In the course of the past 12 months Aiden Whalley and James Young have morphed from a production team into a band, adding vocalist James Buttery along the way, and North, the fruits of their labour, is a fragile, delicate and beautiful record. Tracks like "Gold" and ""Dear Heartbeat"" showcase an 80s synth pop sensibility, forming the backbone of an album that is steeped in worry and melancholia. Buttery's vocal talents add an extra layer of depth to the music, particularly on the poignant, piano driven opening and closing track "In The Wings" and "When It's Gone". There is much to explore on North, which will go down as one of 2010's most affecting electronic albums.
