What does the concert "kitchen" look like from the inside? What path must artists and soloists of art groups take before a concert program is born? How are rehearsals going? Listeners have the opportunity to see all this for themselves! For the performers, walking through the corridors of the Concert Hall and backstage is a normal, everyday job, but for the listener, it is a mysterious, unknown space. On stage we will find instruments that we will get to know and play ourselves.
