Yesterday I went to an interesting talk about "re-performing" Glenn Gould's 1955 recording of Bach's Goldberg Variations. Zenph Studios has developed a very sophisticated method of programming a recorded piano performance into MIDI data, which encodes pitch, intensity, and other control signals. The MIDI can then be played back through a real piano that has motors controlling each key and foot pedals (think high-tech payer piano). Since only the piano is translated into MIDI code, the result is a replication of just the performance, removing anything else from the sound.
Sony got together with the CBC in 2006 to record the "re-performance" of Gould in order to bring the 1955 record into today's modern world of high-fidelity. The result can be heard on Zenph's website. Since the recording only takes up half an SACD, they decided to have two versions from different perspectives. The first is the typical stereo/surround version and the second is a binaural recording from the Glenn Gould's perspective. Designed to be listened to with headphones, this perspective is a really unique chance to hear what the performer hears. There really is nothing else like this... except for the second album they put out with a "re-performance" of Art Tatum live in Los Angelos (1949).
The entire process and idea of a "re-performance" is very interesting. I'm not sure there is much value in attending a concert of this (though concerts have been held). There is little difference between hearing a piano re-create a performance and simply listening to a recording play back through speakers. I also think there is a certain mood or sentimental feeling associated with older recordings. Specifically in this example, Gould was known for humming while playing and this aspect of his performance is lost in translation. Perhaps on that issue alone, the whole process becomes meritless. Is it possible to reduce a performance to pitches, timing, and dynamics? or is a "re-performance" really a completely new performance. Ideas of technology versus art and levels of removal from actual live performance can take over the appreciation of the actual playing. In fact, this really makes more of a statement about the concept of recording and reproduction, becoming a meta-recording. With that said, the new recording of the recording of Glenn Gould does sound pretty amazing.
The album can be found on Amazon.com. For more info check out this article at the Washington Post.
