How The Ever-Loving FUCK!

[Rev. Rye]

It's just a case of "knowing your audience."
To quote the introduction to the very list

One important caveat: we used rock and pop as our rubric, so a drummer's work needed to directly impact that world (as we define it, of course) to make the list. This meant leaving out dozens of essential jazz artists such as Max Roach and Roy Haynes, whose innovations inspired many of the players you'll read about below. That list is its own monument we hope to build someday soon. For now, let the arguments start. If you want to throw a cymbal at us, please do so in the comments section.

So, of course Jazz drummers are less likely to be featured, and probably at disproportionately low spots. (Though at least Gene Krupa is in the top 10).

Case in point, while I haven't found a Top 100 Keyboardists list by RS, I have found a few, and one name that consistently fails to appear on it is Art Tatum.

Fats Waller once introduced him by saying "I just play the piano, but God is in the House tonight!" He's the sort of pianist so skilled that if an urban legend says he learned to play by figuring out piano rolls of tunes meant to be played by two people, nobody questions it. Musicians of all stripes praised him in life. And yet, insanely, of the few lists of the greatest keyboardists I perused, few mention him.
