This is a fascinating TED talk by David Byrne formerly of the Talking Heads. As an enormous music fan who's seen music in many different kinds of venues over the years, the insights in this talk made so much sense. Why did Joni Mitchell kind of fall flat when I saw her in a giant sports arena? Why did The Arcade Fire seem to lose something in the open air? Why can only certain bands fill- both sonically and in terms of numbers- a football stadium? Byrne's talk makes sense of these things. It also brings forth an excellent (four-quadrant) awareness of the interrelatedness of all things in the world. You can't separate the music out from a whole series of possible contexts- the building it's being made in or for; the technology involved in recording or listening; or the needs and behaviors of the social setting. Brilliant.
