Apple Music Festival returns to London 19-28 September for a full-volume celebration of music. A star with staying power, Carrie Underwood is one of country music's most commanding voices; she's sold 64 million records worldwide, earned a stack of awards and found a massive following on the strength of high-volume hits like "Before He Cheats" and "Good Girl". Armed with one of country's most robust voices and a magnetism in the spotlight, Underwood hasn't misstepped once. The freewheeling single "Smoke Break" serves up indisputable evidence that forthcoming album – her first in three years – Storyteller, will continue the streak. Support comes from Camaron Marvel Ochs (known simply as Cam) and The Shires.
