Owed to my father's long interest in electronic music, I'm the thankful owner of several of the 1960s/1970s original print Walter Carlos-attributed vinyl records and a few of the 1980s Wendy Carlos-attributed ones. Switched-On Bach/Brandenburgs, Sonic Seasonings, The Well-Tempered Synthesizer etc. all played a large part in my discovery of electronic music as a child.
Would you be willing to work with an archivist to make these public? (I'm not one, to be clear.) Carlos recordings seem impossible to find!
Her work is not licensed for digital distribution, and largely out of print.
So, there's unfortunately no way to compensate her directly for her works.
And "work" is an understatement. Moog synths of the day were barely instruments. Imagine playing a symphony (symphonic arrangement) using only a single glass filled with water.
You could get any note you wanted, but only one at a time and even that required constant retuning.
