Miles in the Sky and Filles de Kilimanjaro—which tentatively introduced electric bass, electric piano, and electric guitar on some tracks—pointed the way to the fusion phase of Davis's career.

By the time the second half of Filles de Kilimanjaro was recorded, bassist Dave Holland and pianist Chick Corea had replaced Carter and Hancock. Davis soon took over the compositional duties of his sidemen.
