Antonio Vivaldi wrote a mind-numbing number of concertos. With hundreds to choose from, how can one be distinguished from all the others? The Venice Baroque Orchestra treats each as an individual. They gave this performance of Vivaldi's Cello Concerto in A Minor — one of 27 concertos for cello — in concert at Spivey Hall. And they follow it up with an encore: the Presto from Summer, one of Vivaldi's Four Seasons.
