As far as metal goes, I highly recommend Krallice. They've released two albums so far, their self-titled debut from 2008 and Dimensional Bleedthrough in 2009. A third album is coming out some time this year.
Something not exactly "metal", but it fits i guess. They are a cerebral metalish post-rockish band from Bulgaria. I don't know if they are selling somewhere online, though. (Edit: found them on iTunes and Amazon)
Sikth - good mates o' mine from herts, my bro did most of their artwork/videos including this one which I'm in myself! Pin is now in Aliases, the others haven't been up to much Sikth
Mahumodo - good mates, epic music, main guy now lives in Cali and runs *shelsmusic which is a fantastic label Mahumodo
Latitudes - heavy as fuck, riff tastic awesomeness, signed to aforemention *shelsmusic with eden maine's vocalist guesting on. it's very incestuous the scene down here! Latitudes
