There are also plenty of examples of the jazz guys mixing it up with the middle east but not specifically india outside of alice's axis and something like the marvellous 'my goals within' by john mclaughlin, which messes about with ragas a bit.
Good call -
My Goal's Beyond really touched me when I first heard it, still remember the day that i bought it, 19 years ago this summer in fact. Had the Miles-Evans "Blue in Green" and the Mingus "Goodbye Pork Pie Hat" versions on it, but also the sublime Peace one and Peace two.
It's maybe worth recalling that McGlaughlin would go on after
MGB to play with L Shankar, Zakir Hussain et al as Shakti only a few years later, which was yet another example of a jazz-fusion improviser going further still into the realm of indian improv. '74-78 was when Shakti were at their height, overlapping with Mahavishnu 'course. Interesting period.
Memorable story: I remember very vividly when an ethnomusicology professor of mine in my first semester of college played a Shakti record for our class of classical musicians and mentioned in passing that he and L Shankar (from Shakti etc) had been roommates in college some twenty years before. None of the other students had heard of Shakti but my friend and I were huge Shakti fans, so we immediately rushed up after class to ask the prof about him - at that same moment there was an awestruck classical violin student also running up, saying 'how is that possible? there's not a classical violinist on earth whose intonation is as precise as this indian fellow.' The prof just smiled back and nodded as if to say, 'yes, welcome to the world of indian music'
Surely I was the worst on this... sorry Woebot.
