Re: John Bonham (Bonzo)
Two things that mark a great drummer, and Bonzo has them both:
1) You can tell right away who it is playing
2) The parts seem simple and you can look at the notes written out, but you still can't replicated the sound (groove, pocket, feel, etc.)
As for him being dead comment, that's just silly. True, some people's legacy becomes much bigger in death that it ever would have been during life (Elvis, Marylin Monroe, for example). Bonham's skills were never as dubious as many of the other deceased artists.
He may be dead, but some of the greatest rock drumming lives on in the recordings. Even today, people strive to achieve that sound.
Whereas many art forms are striving for new and progressive styles, rock can always fall back on Bonham style drums and do well.
