Nice to see those covers. I have all of those too.
They may not be all transferred to digital,
but they were a solid part of my growing up.
Not sure if what I have is really an archive,
but more closer to a collection of likes throughout the years.
The CDs were just a natural outgrowth of the situation and desires at the time.
Yes, I have digital backups on drives of all kinds of stuff, but I'm not obsessive about it.
They really aren't all that rare (except for the personal bits) because you can buy them
thru the
Stockhausen Verlag (notice the "text" and "rehearsal" links at the top)
or at another CD shop
here. The person running it used to have a nice technical setup
where you could listen to excerpts, but I don't know where it's at now.
The
111 Years Of Deutsche Grammophon set is nice (especially having the
Herbert von Karajan titles together), but DG really wasn't much of a
modern music label, so the "Avant Garde" series was pretty much of an anomaly.
Stockhausen bought the rights back to all of those DG titles and so those
performances are the ones that you get on the discs that he released thru the Verlag.
