Nationally recognized Alabama musician Bobby Horton played popular musical selections from both the Union and Confederate sides of the Civil War in a free concert last night in the Robert and Freda Harrison Auditorium of Giles Hall. The multi-instrumentalist, composer, producer, and music historian's performance was part of his participation in the Social Studies Teachers' Summer Institute sponsored by the National Park Service's Vicksburg and Shiloh national military parks, along with MSU Libraries and the Ulysses S. Grant Association.
