ITUNES FESTIVAL: Plácido Domingo

The star tenor, one of the greatest operatic voices of our era, lets rip on the closing night of the iTunes Festival. He's started in recent years to take on baritone roles as well, including the lead role in Verdi's 'Nabucco' in London last year, and has a huge repertoire to please both the crowds and the critics: expect great things.
