Just to see if I can do YouTubing, here’s Vivaldi’s Trio sonata for two violins and basso continuo (Variations on “La Follia”) Op. 1 No. 12 RV63, performed by Hesperion XXI conducted by Jordi Savall (one of my very favorite musicians):

BTW, not only is Savall a fantastic boon to Renaissance and Baroque performance these days, he is also one seriously lucky dog.  Why? Because he’s married to the soprano Montserrat Figueras:

Mmmm, mmmm.

BTW, if you have never seen Savall’s production of Claudio Monteverdi’s L’Orfeo (in which both Figueras and their daughter both play roles), for Heaven’s sake, get thee to Amazon or Netflix this instant and check it out.  If you have a single musickal bone in your body, you’ll absolutely fall in love with it.
