I cannot remember when last I have been this excited about a band. Alt-J are Joe Newman, Gus Unger-Hamilton, Gwil Sainsbury and Thom Green and they are from the UK. I have been intrigued by their fresh sound and multi layered music for weeks now and just cannot stop listening. Check out a full live set here and their Soundcloud page here. I hope that you will also want to keep going back for more.
