I can't choose one. I have to say all four influenced me. Although my playing ability doesn't approach any of them, I use ideas that still rattle around in my head that came from Baker, Bonham, Moon and Starr.I actually met Ginger Baker several years ago. I told him what an influence and inspiration his playing was for so many of us. He gave me such a surprised look. I wish he'd given me that late 60's A ride with the rivets!
I love the sound of that ride also,and he's still playing it.
As far as influence, I think they all did that in equal measure for me.
But so many others have influenced me also.Buddy,Gene,Louis,Morello,Danny Seraphine,Bobby Culomby,Mitchell,Powell,Danelli,Barbata,Schrieve,Haynes,Paice,Appice,Papa Jo, Elvin,Tony,De Jhonette,Lenny White,Cobham,Gadd,Richie Haywood...I think you see my point.
All of these guys and more, have influenced how I play and my approch to constructing original drum. parts.To me,there is no one greatest drummer in the world.I don't believe that that discussion could possibly exist outside of a highschool cafateria debate on greatness popularity an of course ...speed.Or who won the WFD competition this year.
I have nothing against the WFD,but it has about as much to do with drum set drumming and actually playing the instrument as DNA research.
Even out of those mentioned,I just couldn't pick just one,so I guess....I have to disqualify myself from voting.
