A solo release, "Expectations Of A Sound" is a non-linear sequence of electronic sound work that starts with the early electronics work of Matsunaga, and proceeds through various iterations. The first piece here, a simple vibrating track, opens with a trio of percussion figures, each of which gradually moves in an electronic drift before eventually crashing into one another. The structure is rather simple, with the percussion figures gathering in a pattern, then suddenly disappearing in all directions as the percussionists try to catch up. The other two pieces are more involved, with the drummers working in a more rhythmic fashion, and the percussionists working harder than before to get their points across. The result is a rather thrilling listen.
