King Arthur in the State Opera in Berlin.
Finally I got to see it live and was very impressed with the costumes and stage design. The music and performance was excellent. If your not familiar with this Opera it’s worth listening specially the sacrifice scene (Act 1) and the frost scene (Act 3) are my favorite. The trailer can be found here.
Recording is from 2017 in Schillertheater before the re-opening of the State Opera unter den Linden.
