Oliveros and Deep Listening

[Rez]

Are any of you familiar with Pauline Oliveros and her ideas on "Deep Listening?"  It seems like an intensely focused concentration on sounds themselves.  She is not a pianist but does play the keyboard, or rather (ahem) the accordian.

Her institute offers Deep Listening Retreats that rather piqued my interest.  Anyone ever been on one of these?

It's all described at:

I posted this in the student's corner since it is still about training: the ears rather than the hands in this case.
