Frogman, although I've heard Miles mention "In a Silent Way", it was one of his albums that eluded me. That album was released at about the same time I saw Miles live in Chicago. This wasn't in a club setting, but in a huge auditorium, and somebody bought the cheap seats, consequently I don't remember the personnel on that performance, but I'm assuming they were similar to the record. Nina Simone and Herby Mann were on the same bill, that's why it was in such a huge place.
Miles Davis – trumpet
Wayne Shorter – soprano saxophone
John McLaughlin – electric guitar
Chick Corea – electric piano
Herbie Hancock – electric piano
Joe Zawinul – organ
Dave Holland – double bass
Tony Williams – drums
However, I do remember the sound of that performance and it was what the above cast would produce; electric piano, Tony Williams on drums, Wayne Shorter, John Mclaughlin, electric guitar. That sound coming from Miles Davis was a shock that I wasn't prepared for, but my New Yorker friend clued me in.
Musicians at the clubs I went to began to duplicate that "electric sound". By that time the shock had worn off and I kind of liked it.
Enjoy the music
