It's a young man of 23 named Adam Young from a town just south of Minneapolis - Owatonna, who created his own music in his parent's basement with equipment he purchased for about $4,000. He then proceeded to sell downloads of his music on Myspace, and he made a huge splash. He's now "made it!" He's signing a record deal and will do concerts. He bought a house near his parents.
The thing about him is he's a Christian and he's really sweet. I don't like his music at all, but the lyrics are kind of cool. You can read the story about him here.
