Music Plays Images x Images Play Music is a multi-media concert that uses the system of Toshio Iwai's piano piece and visualizes a real-time musical performance by Ryuichi Sakamoto. During Sakamoto and Iwai's correspondence, the concept for the collaboration expanded rapidly, developing from the simple idea of "Sakamoto playing Iwai's Piano ­- as image media" to a performance that links, in various ways, musical sounds with visual images.
