"Live Electronic Music" by Gordon Mumma is due for release Tuesday on John Zorn's Tzadik label. This release compiles live cybersonic performances dating back to the early 1960s, featuring appearances by David Tudor, Robert Ashley, William Winant and others.
Here's what Tzadik has to say about it:
    "The ultimate document by one of the most important electronic music composers in new music. A lifetime in the making, these meticulously crafted masterpieces include the legendary Mesa performed by avant garde virtuoso David Tudor on electric bandoneon and the first release of the complete version of Mumma's classic composition Hornpipe fully remastered and reworked by the composer himself. One of the most important releases of this or any other year-absolutely essential music by one of downtown's Founding Fathers."

Web author Jesse Niemenen adds that it's "sure to flatten all this glitch-of-the-week stuff churned out by limp-wristed "artists" with thin moustaches and even thinner laptops."
