Hey, rare, you know me.... I'll take another shot!
All metal's roots are heavily in the blues. You can trace it back.
Metal and progressive rock is rooted more in and influenced by classical music.
https://www.youtube.com/watch?v=OTSjrNtz7j8&feature=relatedJordan Rudess, the keyboard player for D.T. has a strong classical background.
and you can definately hear that in the compositions.
Now, jazz is rooted in the blues which is rooted in gospel, which is in turn rooted
in old negro spirituals. But That does not mean that a blues player can play jazz
or vise versa.
A really great drummer in my opinion should be able to play all styles. Drumming is an art, but don't deny it's not also a business.
In regards to this and the rest of what you wrote previously concerning the Juggler,
fire breather, uni-cycler, etc. These are great points. But I think it's the the example
that prompted Pete's question concerning Tony. Is he not multi versed in his craft, along
with many others who
AREN'T getting the session calls? So if this is the method by which
we measure "great" players, then I can boldy say that most of those whom we listen to and
admire are not great at all.
We must not forget that music can be and is broken up into genras. We pick our battles.
Give credit where it's due. Should Buddy Rich not be considered a legendary player because
he decided to specialize rather than generalize? Should a person be considered less than a
great
MUSICIAN based on the fact that he or she plays only one instrument or one style
of music?
Like Dave said, there are many variables. And when we ask questions that go this deep,
we should consider as many of those variables as possible before drawing a conclusion.
Uncle John is among the most musical drummers I've heard. And in contrast, there ain't
that many. Like S.G. John has a way of morphing his ability to the music, becoming part
of the musical signature rather than putting "HIS" signature on it. Few, VERY few can do
this.
