Joe Farrell Quartet

Just as Bitches Brew (1970) pushed Miles Davis's electric music to its peak, his own rhythm players Chick Corea and Dave Holland walked out — turning an off-hours trio into Circle, a free, near-atonal group, rather than chasing the fusion market.

Dave Holland and Chick Corea, who had played on Bitches Brew, walked out of Miles Davis's band at its peak. 'Dave and I could both see Miles wanted to go a different rhythmic way,' Corea said — and the way they went was not more electric fusion but the free-improv group Circle.
