Stewart is bit of an enigma...the 1st takes on the Police tracks captured the fresh magic of playfulness and focus, brilliant stuff of studio improv, still love it. But in the context of a improv interaction like in jazz or jam thing, ...he didn't like it and frankly, didn't play it well either. So it's either hyper-focus improv context for a song take, but the patient stuff improv setting with others seemed to bore him or would make fun of it. To each their own then
A quick personal story, for one of my friend's project he did an unusual arrangement of a jazz standard. I more or less had a preconceived notion how I was thinking the feel to match...played the take and he said "rock it out and fill the space...lets do the take now" of all things, not expected at all. Sure let's rock it out without any preconceived notion, and it worked on the 1st try. Listening back, holy crap I'm totally ripping off Stewart in my own way in both lick wise and my scramble to re-wire approach on the fly. 1st or 2nd takes are always where the best stuff is for sure if you can get it, you have a vibe and energy like not other, the listener hears that edge and fun....The Police tracks certainly did it in a special way. I've borrowed from Stewart on many things, totally translatable for me for creative contexts...find your forward momentum by any means necessary is what I think of, does not have to be conventional.
Music that doesn't stand the test of time?
To much to mention, mostly because it's been overplayed and music audiences has focused backwards way too much...living in the past of yester-year nostalgia. Gun N' Roses comes to mind as a good example that I used to love as a kid and now can't sit through a song anymore.
