Ever heard of Mumford & Sons? My mom told me about this band after it was mentioned in a podcast she was listening to. I think I have a new favorite band. They're a folk band based in London, and they have a slight Irish sound to their music (probably because of the drums) and it's just amazing! On top of that, they're very good singers as well.
(They're not bad-looking guys either, for that matter...) :D
This one is also very very good: Roll Away Your Stone
