How about Mum, Bjork, and Sigur Ros? They're from Iceland. How about The Arcade Fire, The New Deal, Of Montreal, and Godspeed You Black Emperor? They're from Canada. How about Dan Deacon, The Album Leaf, Sufjan Stevens, The Black Angles, and a ton others? Thay're all AMERICAN. Yes a lot of good music comes out of England, but it also comes out of every nook and cranny on the globe.
Open your eyes people, all good bands are right in front of your faces.
