I'd really like some Philip Glass. I think I mentioned it in the other Terry Riley thread.
Yes, Terry Riley is important, because he showed what can be done with a synth, but I still don't think it's music. And no, as you said, it's not ambient.
We need an "experimental" channel here. (And then maybe we can have some Philip Glass at last if we can't have it on this channel?

)
*edit* oh, but not Einstein on the Beach. The badly accented talking on that drives me to distraction. But even as I write, I'm listening to Philip Glass' violin concerto. Although that's too classical for this channel...there's a lot that is nice though, both old and new.
