Mr. Hobson's program, consisting of a very early work by Chopin, which he wrote as a conservatory student at age 17 and performed soon after his graduation two years later, the fifty-year-old Debussy's peak as a writer for the piano, and Rachmaninoff's final work written in Russia: in 1917, when he was forty-four, and his world was crumbling around him, as the Revolution continued its course and he realized that he would have to leave his native country, where he had friends, money, and property, and face an uncertain future as an exile, most likely supporting his family with concert tours in the United States, which he hated. All these works have their harmonic, coloristic, and emotional extremities, at points going as far as to reflect the Paganinian tradition of the demented, or diabolical virtuoso. Hobson responded to this with full sympathy in all, as well as prodigious energy.
