Check out Architects (
MySpace.com - ARCHITECTS - Brighton, UK - Metal / Hardcore / Progressive - www.myspace.com/architectsuk)
I've known these guys since they were 15 and now they're like the biggest metal band in the UK. Mad.
I used to listen to a hell of a lot of metal but now I hardly listen to any. If I am going to listen to any now it'd probably be either Architects, Decapitated, Ion Dissonance or Meshuggah. Maybe Job for a Cowboy might get in there too haha.
