Thank you for addressing some important ideas. As a performer, (not a composer), I have wondered about this myself.

Looking at music history, though, radical ideas have always arrived out of nowhere as soon as people begin to ask these same questions. I think we have been spoiled over the last 50 years by the ability to generate an astonishing range of sonorities possible from electronica. Avant garde has never been so easy!

Where the next wave will break is anyone's guess, but rest assured; it will break.

I remember reading that Varese said something like - "I do not write experimental music. The experimenting is done before I write the music"

I also have to agree that the "next wave will break" as it has been broken from time and time again. We cannot forsee what direction music is headed because we know what we know and all that is before us, nothing more. 100 yrs. ago was the idea conceivable that we would be creating music digitally and have the ability be broadcast it on a worldwide network with the click of a button? The fortuity is part the intrigue that engages us and fuels our passion to explore the possibilities. I have to diagree that all theories and facets have already been realized and circumvented. It is vital we continue to experiment, would you want to live in a world of Brittany and Justins?
