Thank you for describing this "hypnotic transcendental feeling", which I now realize is the common quality that I so enjoy in both Bolero and Terry Riley's "In C" (especially the Ictus & Blindman quartet version https://play.google.com/music/m/Be26kwoxcafkgcyxad6c25y6m3y).

Anyway, now that I've discovered this, I'd love if you'd share some pieces (or a playlist!) that you've found that have this quality?
