These guys were supporting Billy Bragg last night at the Bexhill De La Warr Pavillion. They are a musical collaboration of two exceptional artists from Kentucky, working to raise awareness of mountaintop removal mining, which is as stupid a means of obtaining coal as it sounds. Their music was exceptional and it was most definitely an eye-opener into a destructive activitiy going on at an unbelievable rate.
