II. Time's Arrow
III. Grids and Motors
I'm often struck, when working on a big piece (especially), how the piece changes during the composition process, and just as often, how the original conception remains in the work's DNA. The Percussion Concerto is about time, or rather about some of the various ways time (and its eternal companion, space) has been viewed from Einstein ("Time exists to keep everything from happening at once.") on: fields, waves, arrows grids, and motors.
When I say a piece is "about" something, the scare quotes are honest. It's hard to say sometimes whether the metaphors or the music come first, or whether they generate each other.
