The Rocket Summer is the musical project of Bryce Avary(who I've been a fan of since 2005) he has released two albums so far "Calendar Days" in 2003 and "Hello, Good Friend" in 2005, both with an indie label The Militia Group, but he is signed with Island Records for his third album and I think he may become pretty big because many of his songs are very catchy. The best part about his music is that he wrote all the lyrics and played all the instruments in both of his albums.
Here's the link for his official page(but it appears not to be working rigth now)
