In expert hands, a terrifying 12-tone opera and a heroic piano concerto rattle the walls in Prague’s Rudolfinum.

Olivia Fuchs gives a powerful staging of Janáček's morality tale of the perils of eternal youth, with an excellent cast, but there are reservations about the title role.

Sir Antonio Pappano and the LSO offer a riveting account of Il prigioniero, an idiosyncratic 20th-century opera.
