Gregory Porter explores 100 years of voices on the brink, those that go one note higher, turn it up to eleven and make the hairs on the back of your neck stand on end.

Starting with the world's first pop star, the legendary Italian tenor Enrico Caruso, Gregory explores the sound and work of his favourite vocal showstoppers - the genius of Ella Fitzgerald, the soul of Mahalia Jackson, the power and stagecraft of Freddie Mercury, the artistry and extravagance of Prince, and the modern melisma of Whitney Houston and Mariah Carey. With Dave Grohl, Beck, Adam Lambert, Wendy & Lisa. Show less
