I'm returning to Miles Davis electric period (from 1969 to 1975) and finding the music he created at that time phenomenally creative and innovative. I remember how pissed off many of Miles's fans were when he moved into his 'electric' period, but for the life of me I cannot discern what was so offensive to them? Received wisdom claims that it was the addition of electric guitar that raised so many eyebrows back in 1969. Allegedly, electric guitar has no place in real jazz. But that absolutely doesn't make any sense, because electric guitar had been a legitimate part of traditional jazz for twenty or so years prior to Miles adding it to his ensemble. Charlie Christian had firmly established the legitimacy of electric guitar back in 1941, and following that the scene had seen many brilliant electric jazz guitarists. So why would the addition of electric guitar in 1969 suddenly be perceived by the critics, fans and aficionados as such a treason? To my ears, the music Miles made on the records from that period ("In A Silent Way", "Bitches Brew", "Jack Johnson" and so on) is a perfectly natural continuation of the music he was making during 1960s, during his most celebrated period. Miles was always experimenting, always making sudden left turns, so what's so surprising about the left turn he made in 1969?
