Cantabrigia Five hadn’t been kidding about the sound track. It was a full orchestra, comprising some instruments that would have been familiar to Mozart and others that had been invented thousands of years after Zero. It, and a large choir, poured a three-dimensional ocean of sound into her ears, performing the Red national anthem. Not the peppy, truncated version heard at sporting events but the symphonic arrangement, calculated to make people sit still and be awed.
