I have had this album a number of years now and have used it sparingly in order that it may retain some power to affect me in the manner in which it first did. Not being one to sentimentalise or over egg the pudding, it is a confession, then, to cast my opinion on this performance publicly. There is not a wrong step in this recording and it hits sublime early on and effectively stays there. Perhaps it's the belief, in light of subsequent events, that Miles realised this was his swansong or perhaps the spirit within the performance because he did, but, for whatever reason, there is a vitality within the music that grasps you and doesn't let go. I have many albums by Miles Davis but this, like no other, can take a hold of you and change things around for a while. Try it whilst in a vulnerable frame of mind, late, lights dimmed and a whisky bottle to hand to feel truly human for an hour or so.
