The tired Buddy-Rich-is-the-best-and-no-one-else-will-ever-be-as-good claptrap needs to die. Yes, the man was a freakishly amazing drummer, but it's hardly a stretch to imagine there are many others since who have matched, or even bested, his skills.
Spouting his name is like a default setting these days.
As well, to make THE OTHER tired statement that "rock drummers aren't in the same league occupied by jazz drummers" is proof of ignorance and/or lack of musical creativity of the mind.
Talent is talent and the genre in which talent is expressed is merely a canvas for that talent.
And who is retarded enough to suggest THEY hold the master key of drumming talent quantification/qualification?
Please.
