Just been introduced to this link. Harris is a San Diego-based pianist who, in the course of learning Xenakis’s fearsome Evryali (which itself requires preparing your own performable edition of the piece), drew himself a graph of the various ‘arborescences’ of which the score is composed (here’s another snip of arborescence in Evryali). Harris’s chart is quite a thing of beauty, but even better is the graph that scrolls alongside his own performance of the piece. In so many ways this is an impressive feat of diligence and skill, and it’s terrific to have it presented to the world like this.
