In this piece, harmony and melody are very limited. Harmony is non-existent (if considered as the use of at least three different pitches at the same time) and melody is reduced to one single note, with the only possible combinations resulting in unisons and octaves.
Kakashi is another example of a great record that went into obscurity after its first pressing only to be dug out and rereleased by Better Days and Jet Set Records. Shimizu, a saxophonist and composer, worked with all kinds of musicians and collaborators, including Sakamoto and even artist Nam-June Paik. This record is deeply hypnotic and visits all kinds of soundscapes throughout, always with the saxophone placed at the center of attention.
