I'd have to say a group of lads from the 'Peg appropriately titled:
Electro Quarterstaff
Three guitarists and one drummer. That's it. No vocals.
I won't begin to describe them other than if you are a guitarist or if you are into the differing forms of 'extreme' Metal (or even Metal in general) you should check 'em out. The title of their latest disc, Gretzky, is kinda cool too.
