Composer Elena Kats-Chernin wrote the score, entitled “Fast Blue Air”, for these sound machines. The robotics company Festo sponsored the manufacture and design of the quintet, which were originally presented at the 2007 Hanover Fair. The devices utilize pneumatic components to operate, and are divided into four “electric guitars” and one “drum.” Neat.
