I remain incredibly impressed by David Peacock and Augustine Mayuga Gonzales's combined works. Peacock's arrangements are legitimately incredible, going so far beyond most of the piano arrangements I've heard to make something truly excellent. Likewise, Gonzales interprets them (and just straight up plays them, they're HARD to play), further elevating them.
piano realms: azure specifically also does an excellent job taking water-level music and giving the kinds of vibes those levels have.
Favorite track: Caustics (Original).
