I am not sure there is much difference between body materials all other things being equal. I am certain, however, that suggesting that their might or might not be is a good way to start an argument.

That said, I hope we can all agree that a concrete guitar is a terrible idea. Except maybe for the blues. When I think of a 20 lb guitar I can almost feel the pain it would cause my back, or when I stub my toe on it in a dark room. Or when it falls on something I care about. That's pain and pain is the root of the blues. So maybe for blues.
