After Bob Moog's death one week ago, I found myself listening to everything I have in my collection that was performed on a Moog synthesizer. This includes all of the Carlos stuff, all of Hans Wurmans's material (commercially released and otherwise) that I am lucky to have..it's harder to find..., and that of other artists and non-so-artistic performers. I even listened to my own opus from college electronic music lab and my own subsequent multi-track home studio work with my two MiniMoogs + MicroMoog.
In all of this, there is no way to get around the fact that the original Switched-On-Bach is the paramount of analog synthesizer performances known to me. I estimate that since a grade school music teacher first played the opening track for us when SOB first came out, and I begged my very reluctant, classically trained, serious-musician parents to buy me the LP, that I have listened to the album almost 2000 times.
I am a classical musician, recording engineer, and hear tons of music daily. I never get tired of J.S. Bach's music, and the amazing performances of Walter/Wendy Carlos do not wear thin. I have a pretty good idea of how Carlos put these tracks together, and why, and over what time period and under what conditions. I know how hard it is to pay Bach's complex music well, and I am very familiar with the huge difficulties in even approximating those performance values on multi-tracked synthesizer without MIDI, computer assistance, or sequencers. I also know that Carlos did this work at home using a very limited home-built multi-track recorder and mixer, on an instrument that was not at all refined, even for an early synth. And yet the music sings, and jumps out of the speakers, and dances and lives.
The work of others is simple organ playing by comparison. Carlos did the impossible, and the results are still marvelous today.
