Computer is a song by Bob Mintzer. This is a great song that I played at PMEA Jazz Band. Most of it is a funk rock song, comparable to Chameleon as played by Maynard Ferguson and composed by Herbie Hancock. In the middle and end, the instrumentalists come in, one section at a time, playing a simple little melody. Eventually, the entire band is playing individual simple melodies, and the effect is like a computer analyzing many things at once.
