The Gentleman's Game by Pagan Wanderer Lu. Have you heard the demo of it on his MySpace? It's bloody brilliant. I have it on repeat today. And yesterday. I woke up singing it this morning.
"Matthew's bleeding from his mo-ou-ou-ou-ou-ou-ou-outh..."
I especially love the section towards the end where the guitar goes really skronky for one bar and goes NERNERNERNERNER like a Pavement song or something.
Seriously. Have a listen.
