Saturnalia Special: Do or DIY archive

The 10-year archive of People Like Us's show on WFMU is available at their site, if you want to hear a prime example of collage/free form radio (quite a few hours of it, actually).  The most recent 52 programs are also on a download at iTunes for free, although if you don't already have an Apple password and don't like giving out your credit card info, I wouldn't recommend it.

Peter Schickele: Unbegun Symphony

(10:45) A work unblemished by a single original note.  This version includes the third movement, which wasn't in the original release.  (As he says, there's no first or second movements because he was born too late to have written them.)

Luciano Berio: Thema (Omaggio a Joyce)

(8:11) This is what you do with open-reel tape and the human voice.  At least, in 1958.

The first couple minutes are a recitation by Cathy Berberian of the unaltered text, from James Joyce's Ulysses.  The rest of it is pretty amazing.  "Listen, each and for other plash and silent roar..."

If you like this, there's a longer piece entitled Visage that explores the same approach.
