These lot are really doing it for me right now. I've been grabbing lots of Instra:Mental's dubstep bits for a while now and they are always on point, for me he's been leading the charge of d'n'b people making interesting dubstep along with the likes of Breakage and Martyn. Plus dBridge has always been around and making interesting stuff and popping up on collabs.
This lot now have their own label called NonPlus+ they only have 2 releases so far but hell they are something else. They've inspired me to buy my first d'n'b 12"s for years. Their stuff is so minimal and bleepy it sounds more like a new form of electro rather than d'n'b. Just check out the Instra:Mental track Watching you featuring dBridge and see if you get addicted (its on the myspace).
They have loads on the way too: Nonplus+ is looking rediculess with more from them plus bits from Skream and others. They are working on albums, have releases on some of the best dubstep labels around from Skream's Disfigured Dubz to Apple Pips and Naked Lunch. Instra and dBridge have been colaberating with Burial.
Then if that wasn't enough they do these amazing podcasts showcasing new stuff from them and others plus music that inspired them new or old.
