Sgt. Corrin Campbell is a singer, songwriter, and bassist

Campbell then took her service in a new direction, serving in the Reserve component of the US Army and starting an independent music career in Baltimore, Maryland.  Her ability as a songwriter blossomed, releasing both her first extended play and full-length album with great success.   Over the next several years she toured with her band, performing from the steps of the Lincoln Memorial to 6th Street in Austin, Texas.  In 2010 Campbell was selected to open the Lilith Fair Revival in Columbia, Maryland.  The show included performances by Sara McLachlan, the Indigo Girls, Sara Bareilles and many more.  As her career as a rock artist progressed, the U.S. Army offered her an opportunity to join her two careers in a unique position as the featured performer of Army Musical Outreach.
