On (I believe) the Netflix Miles Davis "Birth of the Cool" documentary, they said that Miles asked Ron Carter to stay on with him when he disbanded his second great Quintet in the late sixties to begin his electrified fusion era with his groundbreaking "In a Silent Way"/"Bitches Brew"/"Tribute to Jack Johnson" trilogy and he turned him down because he didn't want to play electric bass. Some of the material Ron Carter recorded for CTI sounds like electric bass to me although I wouldn't stake my life on it.
Yes. It's Ron Carter himself that talks about it.
He says Miles wanted him to play electric bass and Carter said he would not do it, so he left.
