Das ist ein bisschen kakophonisch, aber die Idee irgendwie auch ziemlich cool: Trainjazz.
Every dot is a real subway train. Eight hundred of them, give or take, form a small jazz combo (walking bass, piano, sax, vibes, brushes) that has been playing without pause for over a hundred years. On the platforms they are hot, screaming, full of complaint. This is the music inside the noise.
