Apple Music Festival returns to London 19-28 September for a full-volume celebration of music. It’s all about that voice; Florence Welch's alto – which can rise from a chill-inducing whisper to a volcanic roar – is the captivating calling card of Florence + The Machine. The group's trio of successively impressive, intricate albums has placed them on the forward-thinking edge of the pop charts. Along the way, Welch has commanded festival audiences, become a fixture of the fashion world, and never ceased to surprise us with her vision. 2015's How Big, How Blue, How Beautiful has all the theatrical drama and emotional fireworks we've always loved, and is their most mature, cohesive album yet. Support comes from James Bay.
