Cheers! Thanks for you compliment and taking the time to check it out!
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.
