Performer: Jiří Rožeň

Nigel Lowery’s new production at Prague State Opera is a gusher of ideas, starting as slapstick but profoundly moving by the end.

Comprised of some 60 musicians from 16 countries, the Ostrava New Orchestra paint pictures of prisons and caves, gardens and machines, in works by students and 20th-century masters.

Calixto Bieito's surreal production of Erwin Schulhoff's forgotten opera takes the audience to the heart of darkness.
