In Stockholm, the capital of Sweden, on the roof of an apartment building, there is a small house behind the chimney. It's home to a "handsome, smart, well-rounded guy in his prime" named Carlson. The writer Astrid Lindgren, who lived in the neighborhood and probably met him more than once during walks, told about him in her books.
This restless, who does not want to grow up at all, likes mischief the most. It's never boring with him, his head is constantly full of all kinds of ideas. That's when he decided to learn to play the trumpet. And not just the trumpet, but all the brass instruments at once! And not only to learn yourself, but also to teach others!
 
You will see how he succeeds in realizing his ideas when you visit the "Karlson School". The new educational program of the Concert Hall is waiting for the most curious children aged 5-11. In it, you will meet not only Karlson, whose role will be played by actor Aurelijus Liškauskas, but also the Klaipėda brass quintet. The event is directed by Nerijus Gedminas, who plays the role of a teacher himself. This is a fun musical event, full of surprises and pranks.
