On the back of the CD case, in the right upper hand corner, like a warning on the back of a medicine bottle, an entreaty:

“Binaural Recording: Please use headphones.”

Even those of you who think they know this masterpiece of experimental electronics by David Tudor (1926-1996) will find here a unique and important collaboration in this production initiated by Pauline Oliveros, then director of the Center for Music Experiment (CME) at UCSD. She invited a group called CIE (Composers Inside Electronics). And the resulting product of that collaboration documented here advances the understanding of this music and will henceforth be an influence on all future performances.

Unfortunately for this writer’s timing, the wealth of information gathered in the course of researching this review, the sheer volume of possibilities in performance and the wider scope of historical and technical elements embraced by this work required a deeper reading and contemplation on my part. In short, it has taken some time for this reviewer to get a grasp of how to express the significance of the deeply substantive work at hand. I simply didn’t know enough about the history of electronic music and the work of this seminal musician.

So now, after some serious study, is my perspective on this landmark composition and, in particular, the deeper significance of this performance. In short, there will likely be many more performances of this work but this one will always be a standout. Not the ultimate version perhaps, but one of the most memorable.

David Tudor was a pianist who championed contemporary piano music and then began a career as a composer. But he was no ordinary composer. Taking inspiration from the composers whose work he championed, Tudor developed musical ideas with structures that contain indeterminate elements within a larger structure. Such is the case with Rainforest which was first developed in 1968 against a cultural backdrop of the height of the psychedelic sixties and the political “days of rage”, a time of artistic innovation like Allen Kaprow’s “happenings” which expanded the concepts of what constituted art, a time of wild experimentation. His work crossed paths with the San Francisco Tape Music Center (which later became the Mills College New Music Center). Tudor traversed some of the same territory as Donald Buchla, Pauline Oliveros, Maggie Payne, Morton Subotnick, Ramon Sender, as well as many others.

The first iteration of Tudor’s innovative and experimental “Rainforest” was in 1968. It is a testament to Tudor’s creativity to have created a structure that contains the indeterminate sonic events called for in the score (not a formal score but a set of performance instructions) in such a way that the piece evolves with each iteration, each performance. That, rather than the varying sonic content, is the heart of this major work of contemporary sonic art.

First, this is a binaural recording, meaning that it was recorded with a technology intended to deliver the sound directly to headphones of the listener hopefully producing an experience much as would have been experienced by sitting in the audience. Earlier versions of this technology involved, basically, microphones embedded in the ear canals of an anthropomorphic head which is placed in front of the performance as a listener would sit in their seat. However, the present recording recording involved another generation of this technology which is particularly well suited to this music. Here the microphones are worn in the ears of the recordist as they meander through the space in which the piece is being performed. The result is the listener being able to (almost literally) get inside the head of the person wandering within the space and listening to the sounds created, sometimes at a distance, sometimes more closely.

Despite the entreaty that the listener wear headphones when listening to this recording (you really should try that at least once), one can play this recording as one would any other musical recording. It can also be appreciated by playing it on speakers in any space as a sort of sound installation. This piece challenges conventional concepts of music and its audience.
