Samuil Feinberg (1890-1962) embodies the type of musician whose creative work extends to several fields simultaneously. In addition to his compositional output, which shows striking harmonic invention, he left behind a number of theoretical writings, influenced several generations of pianists as a professor at the Moscow Conservatory, and enjoyed an excellent reputation over four decades as a profound and sensitive pianist. Feinberg’s music is here championed by Marc-André Hamelin, whose performances demonstrate all its shadows and anxieties while being fully equal to the prodigious technical demands.
