Probably the most under appreciated artist in the world of music. The band became popular for their hit song "Good Day" in 2002. They released their first album on June 4, 2002. Three years later they released their second album on April 19, 2005. With hits like "Buy a Dog" and "Never Ending", this is defiantly a band you should check out.
