You got the "on the path" part exactly right. Over the the past several months I've done some serious listening to the Miles Davis albums from Nefertiti to Bitches Brew, doing the entire stretch a couple of times with repeated listening to some albums. Bitches Brew was the first Miles Davis album I bought during the summer between freshman and sophomore years in college. What I've learned is that each album released was an exploration of material and methods. Miles In The Sky, which I've come to love with repeated listening, was an exploration of both sonorities (with the introduction of the electric piano) and more contemporary dance rhythms. In A Silent Way explored the spaces between the players and what they played. The tracks released on Water Babies help fill in the gaps in the record. Having traversed the available material a few times, the transition from from In A Silent Way's In A Silent Way/It's About That Time to Bitches Brew's Pharaoh's Dance is pretty much seamless to my ears.
