She has scored films, played with rappers, starred in a TV comedy, and performed for the dying. As the classical sensation releases three new works, she talks about the shock of playing arenas – and making the leap into opera

When Caroline Shaw became, at the age of 30, the youngest ever winner of the Pulitzer prize for music, she described herself as “a musician who wrote music” rather than as “a composer”. Partita, her winning score, is a joyful rollercoaster of a work, encompassing song, speech and virtually every vocal technique you can imagine. It was written for Shaw’s own group, Roomful of Teeth.

Eight years on, she’s still wary of defining herself too narrowly. “Composer, for some people, can mean something very particular,” she says, “and I’m trying to make sure I don’t get swallowed up into only one community.” Not that Shaw’s range shows any sign of narrowing: even a small sample of her work over the past few years throws up an array of names not often seen together: rappers Kanye West and Nas, soprano Renée Fleming, mezzo-soprano Anne Sofie von Otter, Arcade Fire’s Richard Reed Parry, pianist Jonathan Biss. She has written film scores, sung on others, was the soloist in her own violin concerto, and even managed a cameo appearance as herself in Amazon Studio’s comedy drama Mozart in the Jungle. A year ago, Orange, a recording of her string quartets, won the Attacca Quartet a Grammy.
