Sergei Rachmaninoff was an example of one of the great “types” in the history of classical music: the virtuoso performer who was also an important composer. And indeed he was one of the greatest examples of this type, because both his performing and his composing activities were on the highest level. During his time, in fact, Rachmaninoff was considered by many to be nothing less than the greatest pianist in the world—and if you go online and check out some of the many Rachmaninoff recordings, I think you’ll see why.
