Respectfully, while I'm about as open-minded as one can be, concerning artistic expression, and love (and play) jazz, that was excruciating. I can literally see the saliva dripping from the bell.
If I were you, I would contact Peter and ask him what MP and reed he is using. I'd be surprised if you received an answer, but it's worth a shot.
I suspect a very soft, fluttery reed, and a wide open, non-baffled chamber and a tip opening above .122. Part of this sound is caused by amplified distortion, and of course-- "technique".
