Ginger Baker and Keith Moon are the reason I started playing the drums. I saw Baker first (with Cream), then Moon (with the Who). I created my drumming style by blending the best aspects of each of their drumming styles. Later I incorporated aspects of the styles of Bill Bruford, Billy Cobham, Tony Williams, Chester Thompson and Phil Collins into my continually evolving drumming style.
I saw the Who live several times in the late 60s and throughout the 70s during the Tommy, Who's Next, Quadrophenia and Who By Numbers tours. I always had fantastic front row seats with an exceptional view of Moon's drumming. Over the years I seen numerous concerts including Genesis, Yes (with Bill Bruford), Pink Floyd, Led Zeppelin, Wishbone Ash, ELP, Mahavishnu Orchestra, Miles Davis, UK, King Crimson, David Bowie, Marvin Gaye, Rush, Supertramp, Bryan Ferry, Sade, Roxy Music, The Strawbs, Michael Jackson, George Michael and numerous other bands. I always watched the drummers and I always listened to how their drumming complimented the music.
Keith Moon was at the absolute height of his creative powers during the Who's performance at the Tanglewood Music Shed on July 7, 1970. The full concert is usually available via YouTube. This is the last time the Who performed Tommy live in the USA. Moon is absolutely on fire. His drumming is flawless. It's smooth, powerful and effortless! This is undeniable evidence that Moon and John Entwhistle are one of the finest rock rhythm sections ever! And that Moon is easily one of the best rock drummers ever, period! As far as him being sloppy, a poor time keeper or technically inefficient, this performance obliterates those criticisms (at least during this time period). He perfectly compliments the music in a distinctive, creative, entertaining and musically powerful way.
Unfortunately, many people have poor visual reference with which to gauge Moon's true genius. It's generally agreed by knowledgeable Moon aficionados that his later performances are marred by lack of practice, the degenerative and de-conditioning effects of the rock and roll life style and boredom. It is because of these later performances that many people believe Moon is deeply flawed and overrated. I saw the Who in 1975 at the Silverdome (in Pontiac, MI) and he was a shadow of his former self.
The most important thing about Moon's drumming is that it perfectly complimented the music in a unique and exciting way. The Who Sell Out, Tommy, Live At Leeds, Who's Next and Quadrophenia are perfect examples of his genius. He did use a high hat (live and in the studio), he took drum lessons and practiced relentlessly (at least in the early days). To me Moon's finest most provocative and creative drumming is on Who's Next, Live At Leeds and Tommy (in that order). Even today, his drumming on these albums is still truly exceptional!
