"Classic FM" the only classical music radio station in Bulgaria celebrates its 25th birthday with a gala concert by the Vienna Mozart Orchestra in the National Place of Culture. As the name of the Orchestra suggests, the musicians are entirely devoted to the works of Wolfgang Amadeus Mozart. The repertoire ranges from all of Mozart's symphonies, through a wide variety of instrumental concerts (for violin, piano and wind) to arias and duets from his most famous operas.
