Love the Tron soundtrack and am happy to learn about Wendy Carlos. Unfortunately, she has fought tirelessly to keep her music from being digitized and available online or streaming. I did however find this delightful collaboration she did with Weird Al Yankovic remaking Peter and the Wolf:
There must be a balance point between greed and control vs letting people enjoy your work. I understand the need for artists to earn a living, but being to restrictive will paint you in to a corner.
In a way she is doing the same to her music as she did to her self; hiding it away from public view
