Bill takes us back over a thousand years to learn the origins of rope tension drums and how the technology evolved over the centuries. We learn about shell construction, head types, guts and snare history, and much much more. Bill is a wealth of information and is the man behind Calderwood Percussion. He is a master drum builder and an all around great musician on many instruments.
