Happy birthday Antonio Vivaldi

Today it's Antonio Vivaldi's birthday.  And so to celebrate, a musical treat.  Not so well known as "The Four Seasons" or his "Gloria", this is his "Concerto a due cori con violino discordato" (RV 583) and it is sublime.   If you are stretched for time, go the 5:20 mark and just listen to the Andante. Turn it up and have tissues ready...it includes a minute of possibly the most beautiful music ever composed.  You will know when you get to the right spot.
