Hawk Nelson
I recently fell into some of this band's music upon a recommendation from a friend. They are a very young band but don't let that deceive you. This four-some from Canada has alot to deliver. Quoting from their website, they are "diehard believers in the transformative power of dreams, planning a course in musical expression at a young age and following through with vivaciousness each inch of the way." I couldn't think of any other way to put it.
Among the songs I've listened to (three), I highly recommend listening in on 36 Days, California, Every Little Thing and As I Was. They are just a great band and I just can't stop listening to 36 days. Get their newest album, Letters To the President.
