Bonham. Him and Moon are my favorite drummers of all time for classic rock. Dave Grohl is an amazing drummer in my opinion for grunge/metal. I love his work with Nirvana and Them Crooked Vultures (with John Paul Jones on bass). He also did the drumming, guitar, bass and vocals for the first Foo Fighters album. He can play lots of instruments, in my opinion his drumming is his best.
