Music by dead white guys

We don't have any music planned for our April in Paris (and Cinque Terre and Venice and Florence and Rome and Naples). This is in sharp contrast to our last European jaunt, where I had at least one concert in mind for each city we visited. If the opportunity presents itself, I'd love to hear some Fauré, Poulenc, or Satie in Paris, some Vivaldi in Venice, or some Caruso-wannabe in Naples. but only if the performers are special. I'm not interested in watching some hacks in 18th century costumes sawing away at their violins.
