Tuned in late to the Bayreuth broadcast, chose Radio Clásica de España to get the commentary. I seemed to break in mid-performance.
First impression: This is not WALKÜRE but the last scene of SIEGFRIED...did I get the day wrong?
Second impression: These are the best voices I have heard in decades...who ARE these people? Is Bayreuth getting it together again, finally?
Sure enough, it is intermission and this was the Varnay/Windgassen/Ludwig/BRSO performance from 1955.
No question that Wagner voices are not what they were 62 years ago.
