Pianists Stefano Bollani and Iiro Rantala bring together 176 ivories to interpret and give tribute to songs associated with opera on this concert recording. The interplay is in a friendly mood, longing on “Caruso” and graceful for “Musetta Waltz” with lots of whimsy and frivolity thrown in, as on the p layful “Te Voglio Bene Assaje’ and “June”. The dynamics are a treat here, taking a wild journey on “Va, Pensiero” while gently prancing on “All’Inizio”. Ride’ Pagliaccio!
