While in Venice we saw and heard a lovely concert of Vivaldi concertos (plus one by Handel) given by this group of musicians known as Interpreti Veneziani. (Four violins and one each of viola, cello, double bass and harpsichord) The acoustics of this church (Chiesa San Vidal) made it quite magical. You can see and hear them much more clearly here: https://www.youtube.com/watch?v=5XR6QwvWDBs
