They weren't all bass drummers. Bobby and Dennis were. Frankie was a fifer. Bobby doesn't come around very often any more; your best bet to meet him will be Deep River or Westbrook. He did the Mariner Muster and Deep River last year w/The Mariners, but that was the 1st time I'd seen him in maybe 10 years or so. Bobby & Dennis are almost solely responsible for the way Bass Drum is played in F&DC today. There are other influences, but those 2 pioneered a new style during the 60's and 70's that has been very widely imitated. Who do you play with? Who's your instructor, Cap?
