Oh yes, this is the good stuff, somewhat evocative of Arvo Pärt's Für Alina, but even more spacious. The closed-ish pandiatonic harmony suits the pacing well, especially with how certain strings ring / sympathize. That walking bassline around 5:50 is satisfying, especially after hanging around, more or less, the middle of the keyboard. i enjoy visiting this minimalist area when noodling at the piano, letting harmony ring out, and breathing in the space, but you've inspired me to live there and see something through to "completion"; fantastic work.
