You either get this or you don't. I got it after a couple of listens and the realisation that the Master had moved on yet again. With this album Miles left many jazz purists behind - understandable, perhaps, as this was the most radical experiment in his electric period so far. I've always preferred the first track - or the 4 tracks which make up the one piece. It has a hypnotic, circular groove which is funky yet spacey at the same time. There is much less of the soloing that jazz listeners would expect - instead trumpet, sax or guitar (John McLaughlin is brilliant on the opening track - or 4 tracks) rise to just above the surface only to disappear again into the mix/mesh. The rhythm section is essentially a drum choir, and Michael Henderson once again shows that he is one of the all-time great bass players, this time holding it all together with the zen-like economy of Aston "Family Man" Barrett. It would be interesting to hear a Bill Laswell reconstruction of the whole album, as he opens Black Satin up to great effect on Panthalassa.
