ITUNES FESTIVAL: Gregory Porter + Eric Whitacre

US soul-jazz singer Gregory Porter got critics, fans and musicians raving with his stunning Grammy-nominated debut 'Water', and he's the real deal live too. He returns to London with his third album, 'Liquid Spirit', and combines the deep soulfulness of John Lucien, the hipness of Kurt Elling and the streetwise lyrical style of Gil Scott-Heron in his prime, bringing an earthy emotional power to all that he sings. Composer, conductor and lecturer Eric Whitacre performs a support set. To win tickets, enter at itunes.com/festival.
