Although they can be a little cheesy, the concerts of baroque and classical music staged in this church (the proceeds go, in part at least, to the church's restoration), may be your only chance to sample a little musical culture while in Florence. Quality is variable, but on the whole a night of favourites (such as The Four Seasons, a little Bach or Paganini) can make for a pleasant evening out. Arrive a little before showtime to get your ticket.
Alternately, walk past the church during afternoon or evening hours to chance upon a free organ recital of variable quality. Step into the dark interior to find a cool respite from the sun, sanctuary populated by just a few lucky tourists.
