Definitely not a metal by any means, but I really like the band A Gun That Shoots Knives and I couldn't find any torrents of them. They are sort of a pop/rock band, but they are very unique and go across a wide variety of genres.
And I don't know if you like hip hop at all, but the band Medium Troy is great. They mix hip hop, reggae, rock, and a bunch of other genres to create some of the greatest hip hop I've heard. They remind me of sublime if sublime had been more focused on hiphop instead of reggae/punk.
These are probably the 2 smallest bands I know of that are on itunes. They both are from the Northwest region (where I live) and haven't toured much yet.
