well, you can never emulate another drummers sound 100%. Its like SRV doing Hendrix, its close, but not the same. Its all about being thrifty with what you doing and not sounding like a drum machine. To many drummers keep it all at the same volume...hats, bass, snare...all the same volume. I think letting the beat brethe helps alot, not staying 100% on the beat all the time. I LOVEEE Frank Beards beats with ZZTOP, he is soo lose of a player. Same with Chad Smith. Try losening up the beat a bit, get your hats open a bit more, then your getting close. Allot of it has to just do with experiance and listing. figure out what works and what dosent. Im still trying to get Moby Dick too as sound as good as it can. Bonzo was soooooo thrifty man, its crazy. Same with Alex Vanhalen.
Listning to Rock drumers in general. The Spirit of Bonzo carries on into sooo many drumers. Daughtry- Break the Spell, 3 Doors Down- 17 Days, Paramore- Riot!, RHCP- Blood Sugar...so many great albums to listen through to hear other drummers and how Bonzo influenced them. Mike Portnoy did a Zepplen cover band, youtube it, he does a great take on Mody Dick.
