Some say he's Scotland's answer to Bonnie Prince Billy. You can stream a song or two here:

He's touring at the moment, i went to see him last Monday. Awesome gig, amazing drummer on some of the tracks and he had a cool supporting folk act as well who seemed to be playing the greatest hits of the 18th and 19th century!
My only regret is he didn't play 'When a man's in love he feels no cold' which is a rare track but worth checking out as it's one of my personal favourites.
