To date, the 26-year-old’s album Ceremonials, the follow-up to her four million-selling, Brit-winning debut Lungs, has sold three million copies since its release in October 2011. It continued into this year with a bang — a British number one in the summer for the album’s fifth single, ‘Spectrum (Say My Name)’, winging its way to the top via a Calvin Harris remix. And, over the past few weeks, there was an O2 double whammy — appearances at the 20,000 arena first with The Rolling Stones, followed by two headlining nights under her own billowing steam. And in between, concerts. Lots of concerts all over the world. In clubs, stadiums, beaches, parks, convention centres, tents, fields.
