O.A.R. first began to develop their unique sound in drummer Chris Culos' basement while in high school in Rockville, Maryland. The band released their first album, The Wanderer, prior to graduating and stayed together throughout college with all members attending The Ohio State University. Recording two additional albums before leaving Columbus, the band began pursuing their musical dreams full time in the summer of 2001. By the end of 2008, the band had released six studio albums and three live double disc CDs.
To date O.A.R. has sold close to 2 million albums and over 2 million concert tickets, including three sold-out shows at New York City's Madison Square Garden. In 2011 the band released their most recent studio album, King, which debuted at #12 on the Billboard 200 chart, #3 on the Billboard Digital Album Chart, and was #3 at iTunes on the day of the release. King was the follow-up to the band's 2008 release, All Sides, which contains the Platinum hit radio single "Shattered." Most recently, the band released a live CD and DVD of their July 2012 performance at Red Rocks Amphitheatre in Morrison, CO entitled Live on Red Rocks.
