a nice clip of Marcia Ball from the Hurricane Katrina Benefit. Marcia is a heck of a blues piano player, and she has incredibly strong hands. A friend of mine let her use his keyboard for a gig in Des Moines. This was a rugged weighted keys digital piano. after the gig he had several broken keys! Its not like she is pounded on it like Jerry Lee, but she can really attack the keys with her hands. Truly amazing!
