I know that's it's almost impossible to classify someone as the best in their field. Being considered "the best" is often a very subjective judgement. However, when it comes to drumming, I will bet you that 9 out of 10 drummers will agree that Buddy Rich was the greatest drummer ever. I have been playing the drums for 40 years and I have watched thousands of different drummers over the years. No one has ever impressed me the way Buddy Rich did. It could be another generation or two before the world sees another drummer with his level of talent. Check out this video of Buddy Rich doing a drum solo.
