Hey snyprrr, what do you mean by "'bluesy' (not in the American sense)"? You've intrigued me with that!
Also with the rest of your description, of course. Enough to look for the quintet for my own self.
But any other sense of 'bluesy' other than American caught my eye in a different way.
Well, hmm,... on YouTube, for Xenakis's Cendrees
, go to Part 2 (out of 3). There is a flute solo of sorts there, and I find it just so jazzy. I guess I'm saying that at a certain point in time, Composers were able to harness the power of sliding into notes better than ever before,... aaand, as good as the more,... er, indigenous types of emoting.
I guess Nordgren's sliding sounds more Japanese than Delta. He's playing a scale similar to that Xenakis Pelog scale (but, more Northern
, whatever that means: Nordgren has a very unique Tone), and sliding in and out of a beautiful melody,... the overall effect for me is a Viking/ancient Japan feeling,... very Conan the Barbarian
, but in the best sense possible (try not to see Arnie),... perhaps Magnus Magnusson, if you know who that is (a writer). I know this is terrible, haha!! The point is, it has that deeply 'felt' feeling written into the music, I believe.
Yes, I made the Xenakis/Conan/Memphis connection!!
