What is different is that Teo's mojo reached full flower here. I don't know that anything other than "Rated X" was so fully a Teo joint.
The original record was a gloriously muddymuddled mess. But as time goes by and they clean it up...good lord, ALL the loops and splices, there's a reason why a younger set of ears reveres it. Those types of things were supposed to stay hidden. Here, they are the whole point.
As for the critics, in real time, none of them got it. Even the ones who had "nice' things to say about it. To be honest. I don't think that anybody got it except Miles and Teo and maybe some of the same folks who were buying Funkadelic records when Funkadelic was a rock band. People who already had different ears to begin with. And then only dome of them.
But hey, these things take time.
