Ensemble Allegria is also this year at OBOS and The Norwegian Opera and Ballet's magical Christmas concert, exclusively for OBOS members. Fire shows, 11 and 18 December.

OBOS and DNO&B welcome you to the main stage in a Christmas-decorated opera house when they invite you to a Christmas gala in the Opera. The program includes both "O weekend night" and "Deilig er jorden", and you can experience some of Norway's finest voices singing Christmas.

The concert is only for you who are an OBOS member, accompanied. You can buy up to four tickets per membership.

You can get tickets on OBOS' member pages.
