A program of musical mystifications in virtuosic performance and in a cosmic atmosphere - on the most mysterious holiday of the year. Get ready to be amazed! Halloween is a great occasion for musical discoveries. Planetarium No. 1 invites you to immerse yourself in an atmosphere of mysteries and historical detectives at a themed concert dedicated to musical mystifications. Performed by the king of instruments - the organ, as well as violin, piano, and cello, under the impressive dome with a projection of the starry sky, works by authors who signed under the names of other composers or maintained anonymity so that their works would resonate through the ages will be performed. Additionally, compositions whose authors have never been identified - and remain a mystery to this day. Performers include leading musicians from St. Petersburg, laureates of international competitions, soloists, and guest musicians from the Mariinsky Theatre and the St. Petersburg Philharmonic. Concert duration: 1 hour without intermission. An annual costume contest will take place at the concert! Guests can take photos in Halloween costumes. Two winners will receive a pair of tickets to any Amadeus Concerts event until the end of the year. Detailed conditions will be announced at the concert.
