As pianist, Rubinstein was distinguished for his grand style, broad and noble mastery of the instrument, and his consummate sympathy and innate musical quality. He was a player of moods, at times playing like a god, at other times his work disfigured by many errors, but always interesting, commanding and noble. He played best the compositions of Beethoven and Schumann, their innate depth and intense musical expression appealing to his richly gifted musical nature irresistibly. His personality was commanding and attractive. Saint-Saens relates how Rubinstein played in Paris the concertos of Beethoven and of Rubinstein, while Saint-Saens conducted the orchestra. At the close of the concerts Rubinstein desired to give yet another in which he himself would direct the orchestra, while Saint-Saens should play. It was for this occasion that the Saint-Saens second concerto was written. In his later life Rubinstein lived like a prince in a beautiful estate near St. Petersburgh. The list of his works is something enormous. Of operas and dramatic works there are twelve, several of which, such as "The Tower of Babel," "Paradise Lost" and "Moses," are biblical operas, a type of dramatico mystical work created by Rubinstein. It contains the gravity and depth of oratorio combined with the intense realism of the stage. There are six symphonies, of which the famous and several times enlarged "Ocean" symphony is perhaps best known, a "Heroic Fantasia" for orchestra, three character pieces for orchestra, "Faust," "Don Quixote" and "Ivan"; three concert overtures, a quantity of chamber music, compositions for piano, songs, and the like. In everything of Rubinstein beautiful melodies are found; his weakness lies in the development, which occasionally is carried too far, and with insufficient vitality of thematic work.
