Time to reconsider?
I haven't liked Stockhausen much in the past, despite giving him a number of serious tries.
However, I'm willing to reconsider. To that end, I ordered the Eötvös recording of Gruppen and Punkte, and it will be waiting for me when I arrive in Chicago in a few days.
Years ago, I had the Abbado recording of Gruppen, but it really didn't stick to me. I've read in a number of places that it's generally considered to be not very good, and fails to bring out the spatial aspect of the piece sufficiently. So, here's hoping Eötvös will come through for me.
