In 2017, we turned the famous Art Nouveau post office building on Jindřišská Street into a concert hall. We invited the Czech Radio Symphony Orchestra and pianist Miroslav Sekera (who played the young Amadeus in Forman's film of the same name when he was five years old), who played Mozart's Prague Symphony together with cellist Tomáš Jamník. Admission was free. When visitors walked in with a letter to send in the post, the space they once knew so well was not the same.
