A few random thoughts:
It's regrettable that jazz has been taken over by academia in this way. This sort of writing - endemic in many academic areas nowadays - is quite alien to the spirit of the music and, quite frankly, insults it.
An artist friend of mine, whom I won't name, produces writing of this sort about his own work. When I visited his art show and liked the work - finding it even entertaining - I told him I'd feared the worst after reading the incomprehensible gobbledegook he'd written about it. He laughed and said he only wrote that stuff to send people up and tie them in knots.
Perhaps the best policy, then, is to ignore the academic writing and enjoy the Coltrane disc.
I'm very happy, though, about academia's taking up of jazz in another way - the practical courses which now abound in learning and playing the music. These are keeping the music alive and generations of musicians - as far back of Jimmy Giuffre - are now the products of such courses. Teaching on these courses is also a valuable source of livelihood for musicians, particularly in providing pensions when the continual touring and playing become too much to sustain.
