David Tudor and I went to Hilversum in Holland to make a recording for the Dutch radio. We arrived at the studio early and there was some delay. To pass the time, we chatted with the engineer who was to work with us. He asked me what kind of music he was about to record. Since he was a Dutchman I said, 'It may remind you of the work of Mondrian.' When the session was finished and the three of us were leaving the studio, I asked the engineer what he thought of the music we had played. He said, 'It reminded me of the work of Mondrian.'
