The Krasnoyarsk audience knows the opera Night at the Museum or the Testament of the Master by Pyotr Pospelov based on Wolfgang Amadeus Mozart's sonatas as part of the project The Art at the Quadrat; the events of the project usually take place in the art space loft Quadrat. However, the Hvorostovsky Krasnoyarsk Opera and Ballet Theatre will host the show on November 27 and 28, 2021.

The spectators’ seats will not be located in the hall but on the stage. This seating arrangement is known to those who attended the events of the Art Cafe project when they were held on the stage (and not in the foyer, as usual). The luxurious scenery of this chamber opera, full of mysticism and miracles, will be fully transferred to the theatre’s stage from the loft Quadrat.

On November 27 and 28, both casts will perform Nights at the Museum: Zoya Rzheplyanskaya and Inna Spodina as a Tour Guide, Daria Ryabinko and Natalia Plotnikova as a Guardian, Eugeny Sevastianov and Alexei Sokolov as a Security Guard. Andrei Kolobov and Vera Izotova will perform the Director and a Janitor both days.

All kinds of trials, torments, and adventures fall to the lot of the four characters of the opera. The protagonists will try to master the secrets of the Master, they will look for the philosopher's stone, decipher Don Juan’s list, hold a seance, cook love potions: their goal is to get closer to each other.
