Best rock drummers in my mind may not be necessarily the most talented, but the drummers that perfected provided a back drop to the rhythm of the guitar and song. That said, I will cast a vote for Alex Van Halen
Best Rock Drummers
I've seen most of them and by far the two that stand out are Neil Peart of Rush and Ceasar Z. of Golden Earring. For non-rock I would say it's a no brainer with Buddy Rich.
