Sorry I usually do not mention music, since that cannot be experienced in the photos... But research indicated music is by Rimsky-Korsakov, from operas (Sadko, Le Coq d'Or, Mlada, and The Invisible City of Kitesh), the third symphony Antar, and the tone poem Skaza. It was arranged by John Lanchbery. I can obtain the playlist from the production staff if you are more curious.
