Recorded in a variety of informal and formal non-public situations between 1967 and 1976.Includes "the ’Four Room Session’ of March 1973:... performers were isolated in four completely,separate rooms (connected... by microphones and headphones). Following a strict time schedule, the performers grouped and regrouped themselves in the four rooms... using nothing but theirears to guide them...."
It's on vinyl, under the corn pride label. YES.
For the less, um, adventuresome among you, there are hundreds of choral and chamber recordings, with a broad swath of repertoire.
At a time when artists (as ever) have been forced to justify the public investment in them, reciprocating state funding with goodwill gestures that make performances, recordings--and scholarship--more publicly consumable and accessible seems like a fair trade. I have a friend, a terrific computer musician, who has arcane interests in 1960s information theory. Making an honest living as a programmer and touring musician, however, he lacks access to a lot of walled research consortiums and recording databases. He's highly trained, and--arguably--does as much to spread knowledge about computer music than any professor. He once tried to buy a study of Lejaren Hiller, only to find the $200+ price tag prohibitively expensive.
We should be paying people to read books about Lejaren Hiller. There are thousands of people like him, highly trained musicians looking to engage and celebrate their craft beyond the academy, who are omnivorous and hungry consumers of musical content.
Let's be real--the commercial implications of a "four room session" are, will always be, and have always been, absolutely negligible. But as a document, it's absolutely vital that we share what we do and what we've done in order to better articulate why we must do it.
