This rendition from Spencer Myer is particularly thrilling.
Ohhh listen to the strange, but altogether delightful harmonies, inner melodies, and motifs. The wide span of dynamics this piece encompasses is just amazing. And its tonal edifices - superb. This is going demand lots of concentration, comprehension, and communication from the performer.
I really wanna learn this.
