Today it’s raining. I can hear the drops on our metal roof. This is how it was when I was working on the Rain Sequence of Aberfan — realizing that rain falls haphazardly, scattershot, as if random. Yet it is a precisely created pattern.
Here is the very beginning of Aberfan, a few minutes of rain, one piano entering after the other.
