Widely considered the most important of the Russian nationalist composers, Moussorgsky finished relatively few works in the course of his tragically short life. His unorthodox techniques made a considerable impression on later composers. A Night On Bald Mountain, is a brilliant example of Moussorgsky's unique sense of theatrical effect, and was completed and orchestrated by Rimsky-Korsakov after the composer's death. This work is a staple part of the orchestral repertoire.
