Julian Anderson, one of the most distinctive composers of his generation, has never been to the Czech Republic, yet he knows more about the country than the vast majority of Brits. Although he has never set eyes on Prague, he has fallen in love with the city and is currently composing a symphony about it. Called Prague Panoramas, it was inspired by Josef Sudek’s black and white photographs of the city, and is due to premier this spring in Prague’s Rudolfinum Music Hall.
