In 10 years Graham Sheffield and Sir John Tusa have turned around London’s Barbican. “This dynamic duo have managed to turn a derided behemoth into a cultural powerhouse. Once a byword for unfashionability, the Barbican has become a home for cutting-edge experimentalism and music and performance from around the world. Meeting them in the flesh, the two actually put you in mind more of another high-flying double-act that started out at roughly the same time – that of Tony Blair and Gordon Brown, albeit without the acrimony.”
