4. Ancient Mariner
folk/indie/progressive rock http://youtu.be/lEg0EhClV8Y At the best of times folk music can be some of the most introspective music to lie back and get lost in thought with, and when the best folk is at its introspective best it can be a truly beautiful and spectral listening experience. What makes it even better, as with most music, is when it's not afraid to step outside its genre boundaries and take in the influences and elements of like minded but stylistically differing music. Ancient Mariner are one such duo, taking a sold grounding in a melancholic but emotionally rewarding kind of folk, they also bring in shades of indie and alternative and just a little hint of spacious and dreamy progressive rock; kind of like if Radiohead did folk music.
