a propos of hitting Bflat ...or who knows what other peaks... Remember having seen an ORIGINAL "Rigoletto" in Vienna made by Abbado... it was very nice and it was ORIGINAL.... but it was like a very nice night sky without stars... sorry!
I posted this coz the sound of the video-posting from the 60' is kind of broken at the end.... and the end (among others) counts.... this recording is from the early 70'....
