The Wind That Shakes The Barley - It Bites.
First heard this song on 106.1 Rock Radio Manchester on me way home after the Villa game this season in March, completely blew me away! but i've listened to the rest of their stuff and i ain't keen at all!
I then learnt a few days later their very popular and have been about a very long time, can't believe i've never heard of them before!
