Merce Cunningham on his Radiohead collaboration: “Well, I don’t know that much about rock bands, but it was a new kind of sound. I thought, ‘Well, that’s interesting.’ As music is greatly concerned with sound and, as John Cage would say, silence, I thought, Well, we’d never done anything like this before, so why not try it?’ But what started out as a relatively simple idea – find an open-minded, nonconforming composer with whom to collaborate on a new piece – quickly became a more complicated venture than Cunningham had ever encountered.”
