M. de Pachmann, the famous Russian pianist, is among the few artists capable of filling St. James's-hall by his unaided efforts, and that feat he accomplished yesterday afternoon, when a large audience assembled to witness the first of two pianoforte recitals announced by him. The programme was as varied as it was interesting, most of the modern masters of the instrument, from Beethoven and Weber to Henselt, Chopin, and Raff being presented. All this music was played without the aid of a book, and, barring a momentary slip of memory, without a hitch, the artist thus proving his versatility, no less than the refinement of touch and phrasing which have made his reputation.
