"Memories of Green" (from the album "See You Later") https://www.youtube.com/watch?v=pW9D6agp794
I think this piece shows the range of his musical expressiveness, apart from his virtuosity or synth programming skills. Just a piano passed through a flanger effect with some ambient sounds.
The electronic bleeps in that track are recorded from a handheld electronic game (Bambino UFO Master Blaster [1]). Talk about giving a whole new meaning to those sounds.
