@onhwy61: Good points. Yes, a musician is called upon to provide whatever the music being made calls for. Very, very few musicians are proficient in all styles. Guys like Steve Gadd are thin on the ground. It pains me to hear Rock drummers trying to play Jazz, or even Country. When The Byrds went Country, they unfortunately took in Gene Parsons, a drummer who did not understand what was appropriate for that genre of music. For me his drumming ruined The Byrds albums he played on. Waaay too busy---"fiddly", with syncopated kick drum. Dude, you’re stepping all over the other player’s parts, not to mention the vocals.
In one of the Bobby Whitlock videos he is asked about Keith Moon, with whom Bobby during his residence in England became close friends (Bobby lived with Clapton for a year, then with George Harrison at Friar Park for about six months, eventually getting his own house). He is asked if he and Keith ever played music together, and he immediately says "Oh no", then goes on to explain why.
Bobby was the 1st-chair drummer in his High School marching band, and very well understands drumming. Bobby then plays "air drums", displaying the drumming style that Keith was unable to play in, the style that is required in the music Bobby makes. He then says Keith could play other stuff, but not the meat ’n’ potatoes Rock ’n’ Roll/Blues/R & B that Bobby plays. He mentions Al Jackson (Booker T & The MG’s), Jimmy Karstein (a great, great Tulsa drummer who played with Dylan, J.J. Cale, T Bone Burnett, Delaney & Bonnie, Leon Russell, etc.), and the astoundingly-great Roger Hawkins (that’s him on Boz Scaggs’ debut album, Paul Simon’s Kodachrome, and all of Aretha’s Atlantic albums). Horses for courses, as the expression goes. English drummers are notoriously inept at playing American Roots music, not understanding how to create the deep pocket/groove/feel absolutely essential for the music. Listen to Hawkins drumming on Wilson Picket’s "634-5789". Sounds easy? Try to replicate it!
Though born and raised in Southern California, Jim Gordon could play as if he was a Southern boy. That’s especially mystifying as he came out of the L.A. studios, playing on an Everly Brothers date at age 17 (!). Jim Keltner was the drummer in Delaney & Bonnie’s band, and he switched places with Gordon, Keltner moving into the studio, Gordon going on the road with D & B, where he first met and played with Clapton. Not commonly known, Jim Gordon also had enough technical ability to work with Frank Zappa, a very demanding gig.
