Great Northern sounds a great deal like Elliot Smith, with a tiny bit of The Cranberries thrown in for good measure. The overall style is mellow, with haunting vocals that are reminiscent of Sun King by The Beatles. The sound is consistent, and the samples available are a good indication of the entire album.
It really is Shoegazing music, but the vocalists are too powerful to be firmly put in this category.
If there is any criticism worth a one star deduction, it is that the music itself, while well orchestrated, is a bit simple. Contrast that with Smith, who threw a lot of goings on behind his melodies, and made for far more interesting compositions.
