In no particular order ....
Mitch Mitchell (Jimi Hendrix Experience) - manic stuff, the perfect foil for Hendrix's playing.
Keith Moon - completely bonkers and his drumming reflected that.
John Bonham - monstrous sound and great invention.
Neil Peart (Rush) - the only man (apart from Bonham) ever to do a drum solo which didn't bore me.
Ian Mosley (Marillion, among others) - understated, unfussy and always right on the money.
Will Calhoun (Living Colour) - can drum in absolutely any style from thrash to jazz to African pop - amazing.
Dave Grohl - the only man who could ever replace John Bonham in the extremely unlikely event that Zep tour again.
Dominic Greensmith (Reef) - live he was always right on the money .... much more inventive than the band's music would suggest.
