Performer: Henrik Engelsviken

Christoph Loy's Oslo production of Wozzeck is a dramatic triumph, with gripping performances from a cast led by Audun Iversen's desperate title character.

Despite occasionally brilliant singing, the Norwegian National Opera fails to raise seasonal spirits with a dramatically inert Cavalleria rusticana and a shaky Pagliacci.

Despite an excellent cast and some glorious singing, Stephen Langridge's oft-revived 2012 production of Puccini's Madama Butterfly never quite takes flight.
