Found this band via Marco Arment. You may enjoy them as well if you like folksy songs with a touch of acoustic guitar magic.
Their first two albums are supposed to be available for free on their website but perhaps because of the Marco Arment tweet, their Dropbox account is suspended due to too many downloads.
Their 3rd album, the Grammy nominated Ash & Clay, is available on iTunes.
