So imagine you really like music and you want to make your own music, but instead of using instruments like guitars or pianos, you use machines and computers to create sounds. That's called electronic music.
The Columbia-Princeton Electronic Music Center was a place where people who liked electronic music could go and use all sorts of machines and computers to make their own music. It was like a big playground for music lovers!
They had things like synthesizers, which are machines that can make lots of different sounds, like an elephant or a spaceship or even just a beep. They also had tape machines, which were kind of like big tape recorders, that could edit and mix sounds together.
Lots of famous musicians went to the Columbia-Princeton Electronic Music Center, like Pauline Oliveros and Mario Davidovsky, and they made all sorts of cool music using the machines there.
And the Columbia-Princeton Electronic Music Center album is a collection of some of the music that was made there. It's like a big musical treasure chest that lets us hear what people made when they got to play with all these amazing machines and computers.
