David Byrne gave this great talk at the TED 2010 conference. It's worth 15 minutes of your time:
Byrne makes a number of excellent points, and has a very enlightened perspective on the acoustics of performance venues that I have found (unfortunately) all too lacking amongst musicians and composers. Byrne's points also relate in interesting ways to the talk I gave at World Voice Day called There is No Perfect Sound. You can watch my 30 minute talk here.
