Summertime's End is Daniel Throssell, a 19 year old Australian who makes music. His sound is a lot like Owl City and Relient K. The music itself and the lyrics are very uplifting.
"I believe that Jesus Christ is the way, the truth and the life. In Him I have peace, comfort and strength. If you are burdened, please repent of your sins and reach out to Him, for He will not deny you, and you will forever delight in His glory - in this life and the next."
