The act of playing in a rhythm section and accompanying a soloist as a cohesive unit is an art in itself. These cats really set the bar for how it's done. Miles knew that and that's why he hired them !

Jimmy Cobb - Drums
Paul Chambers - Bass
Wynton Kelly - Piano
(...and some tenor player)
And on this clip Oscar Peterson sits it on piano and Stan Getz joins Coltrane on Thelonious Monk's "Hackensack":
