The Beaches Chapel next to the museum in Jacksonville Beach holds great concerts. Check out http://beachesmuseum.org/index.html
Last Night I volunteered to photograph Calvin Newborn, and a musical Quartet. Calvin played and recorded with BB King and many other greats and at 82, is still touring occasionally. Three hours of great music and in a fabulous venue. It was difficult to shoot without a flash and was extremely dark. I had my cameras at very high ISO.
