Perhaps the most famous performance of the "1812 Overture" took place not in Russia or in Europe, but in America. Boston Pops conductor Arthur Fiedler was no doubt inspired by the overture's exhilarating musical structure when he decided to include it as part of his 1974 Independence Day performance.
