My current project is creating a new performance version of Williams Mix. I have received the score from the John Cage Trust and am measuring and noting all of the tape edits from the original 192 page score. This detailed information will be used to create a computer music program or patch with which I can perform the piece. I do not think anyone has taken this approach yet.
Soon I will be putting out a call for sound file contributions to this version. I will try to cast my net wide, as Cage’s original note calls for “all acoustic phenomena”. However, if I miss you and you would like to contribute to this project, please get in touch.
