(Samuel Vriezen)

Also known as Toccata IV, The Weather Riots was written for Number Night, which was part of Concerten Tot en Met, a concert series I organized dedicated to new and experimental chamber music in Amsterdam. The idea behind Number Night was that the notations invented by John Cage for his late works such as Music For... and the "number pieces" could be seen as defining a genre, similar to Mass, Fugue or Sonata Form, that can have stylistic meaning beyond Cage's own style and aesthetic interests. I asked six composers to write new pieces based on Cage's stopwatch notation, The Weather Riots being my own contribution.

The piece is written for a minimum of two and a maximum of a few thousand of high instruments, which may include flutes, clarinets, oboes, pianos, vibraphones, violins, etc. In The Weather Riots, each performer plays his/her own version of the same part which (s)he has prepared in advance, choosing for each 'time bracket' a number (1 to 6) of melodic fragments from a given collection of fragments. These can then be combined in many ways. Inevitably, there will be echoes or other relations of similarity between the parts. The fragment collections themselves change shape slowly over time, sometimes foregrounding certain contour types, sometimes certain harmonies, sometimes certain articulations, sometimes broadening scope, sometimes narrowing scope. They define the musical space that the performers each can articulate in their own way: a counterpoint of personalities.

This recording is the original performance at Concerten Tot en Met by the incidental ensemble for the concert, the Number Night Ensemble, at the Posthoornkerk in Amsterdam.
