It is difficult to say which was the better pianist. In every way as different as the brothers were in personal appearance—the one dark, almost to blackness; the other very fair — so different was their playing. The playing of Nicholas was more like that of Tausig, only warmer and more impulsive. Perhaps Anton Rubinstein was the more inspired player of the two, but he was unequal. Nicholas never varied; his playing both in private and in public was always the same, and he kept up the same standard of excellence.
