The stage composition is dedicated to the relationship between Pyotr Ilyich Tchaikovsky and Nadezhda von Meck. The final event of the festival Per aspera ad astra! - a literary and musical evening dedicated to one of the most mysterious and exciting episodes in the biography of P.I. Tchaikovsky. The main characters are he and Nadezhda Filaretovna von Meck - his patroness, with whom the composer had a rich, deep, and emotional correspondence for 13 years. Never meeting in person, they managed to create a rare spiritual union. The evening is designed as a musical-dramatic narrative, where artistic word and music intertwine into a single romantic plot. The letters will be read by actors Larisa Demidova and Viktor Nikitin, while Tchaikovsky's music will be performed by Elena Kozhina (piano). The concert is timed to the 185th anniversary of Tchaikovsky's birth and concludes the program of the anniversary festival in honor of the 25th anniversary of the Losev House.
