Hi,
The cut with Tangerine Dream ... has been on the TD website for a while with a link for it. I haven't even heard it yet, believe it or not. Keep forgetting to check all the links when I get home!
The one piece that is nice and worth listening to, is the link for Jerome Froese's (son to Edgar) final piece with his dad and/or TD ... which is really nice. Jerome is much more "modern" than the style that Edgar had been into, but the piece is very nice, and it's cool to hear dad play.
The news on the new stuff coming out, btw, is a bunch of hogwash so far ... Peter Baumann (original TD) was gonna help and now he has left ... probably because he is not on par/sync with all these new fangled instruments, is my guess!
