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.
Mussorgsky's works, while strikingly novel, are stylistically Romantic and draw heavily on Russian musical themes. He has been the inspiration for many Russian composers, including most notably Dmitri Shostakovich (in his late symphonies) and Sergei Prokofiev (in his operas).
Mussorgsky's most imaginative and frequently performed work is the cycle of piano pieces describing paintings in sound called Pictures at an Exhibition. This composition, best known through an orchestral arrangement by Maurice Ravel, was written in commemoration of his friend, the architect Viktor Hartmann.
