Vladimir Sergeyevich Rosing, also known as Val Rosing, was a Russian-born operatic tenor and stage director who spent most of his professional career in the United Kingdom and the United States. In his formative years he experienced the last years of the "golden age" of opera, and he dedicated himself through his singing and directing to breathing new life into opera's outworn mannerisms and methods.

Modest Petrovich Mussorgsky was a Russian composer, one of the group known as "The Five". He was an innovator of Russian music in the Romantic period. He strove to achieve a uniquely Russian musical identity, often in deliberate defiance of the established conventions of Western music.
