It occured to me a moment ago, as I'm listening to a Jakob Ullmann record on Editions RZ, that I have loads of CDs from this label. And then I looked at its roster, which is just insanely brilliant - Ullmann, Lachenman, Xenakis, Cage, Radelescu, Tudor, Koenig, Nono, Lang, Kibusch and lots of people I haven't heard of who must, by proxy, be awesome. So yes. Edition RZ - my new favourite label.
