i didn't like keyboards in rock untill i really analyzed what Dizzy does. Now i love them if they fit in context ( obviously, metallica shouldn't consider it), but i don't like dizzy with pitman.
Consider this, lets say they play november rain, thats axl, dizzy and pittman on keys, and now with buckethead out, i mean, more keys than guitars in guns n' roses, i mean, try telling that to someone in 1988
