As a soloist, he excelled in performance and was especially noted for stylish interpretations, his refined temperament, and beautiful, expressive tone.  In his later years, he became a professor at Moscow Conservatory, and continued to perform well into his later life.  Although his popularity is obscured by the more famous composers and virtuosos, his influence on those composers' most prominent compositions is evident.
