Wonderful stuff !!! Thank you for that.
I am a great baroque afficionado ( and before that,I adore eg Ockeghem ) and one of my favorite singers is the French countertenor Philippe Jaroussky,here with a Vivaldi Aria.
The re-discovery of Vivaldi as a high quality opera composer is one of the highlights in baroque "musical discoveries" in recent years.
