Pauline Oliveros was a pioneering electronic as well as instrumental composer.
She is well-described by
her obituary
in the New York Times. Her key contribution is the practice of "deep listening."
Deep Listening (1989)
Oliveros, Stuart Dempster, and Panaiotis decended into a very reverberant,
two-million-gallon cistern below a decommissioned U.S. Army base in Washington state.
This work is the result. Listen to several excerpts of your choice.
I recommend 20:00 through the end.
Oliveros with her Roland V Accordion
Examples of sound she gets on the accordian, and its relationship with electronic music.
A Love Song
Listen to this in its entirety.
Alien Bog (1967)
One of her earlier electronic compositions.
Listen to three or so randomly chosen excerpts to get the idea.
Optional: listen in its entirely for a mesmerizing experience.
