Thanks for your response. I'm always learning something new from your posts !
Perhaps my ear is simply not sufficiently acute to perceive the dominant "Jazz/Rock sensibility" you pick up on in Potter's playing. Or perhaps this is simply a result of my not having heard him in enough settings to form a more rounded opinion.
As far as abstraction is concerned, it was not atypical for the Dave Holland Quintet (live at least) to venture "outside". The music could get fairly Free during such interludes. You might have disagreed with me had you been sitting in the venue but at such times, but what was played did not in my ears/brain, evoke associations or parallels with/to Jazz/Rock's harmonic language. More like Freed-up New Orleans style simultaneous improv.
I now see I misunderstood your original comment. I didn't consider whether Miles would've found Potter's playing in synch with his vision at the time Shorter was enlisted. I'm sure you're right that Miles was not looking for a Coltrane disciple at that point.
Finally, regarding the link, Shai Maestro's playing sounds quite Pop-influenced to me. That's not something that, to my ear, figures strongly in Dave Holland's compositions, so I wouldn't expect Potter to respond the same way. Having said that, I'm not a professional musician. No doubt there is much that is obvious to you that I miss!
