By the way, it is a year or two since I last looked at the Austrian Radio web-site, and I see that they now do "on-demand" for the past seven days. A useful improvement - must give it a try!
I've tried to record this concert directly via my cable connection (in order to get the best digital quality),
but for OE1 no data has been transmitted. So I had to stay with their "on-demand" service, which unfortunately
is only of moderate audio quality (96 kB/s).
So I hope you have got a better recording of it.
