Besides being a great composer, Sergei Rachmaninoff (1873-1943) was also a marvellously accomplished and original performer on the piano, an instrument which has never lacked outstanding players. He cut gramophone recordings between 1919 and 1942, a period during which many improvements were made in the quality of recorded sound. Yet by 21st-century standards Rachmaninoff’s work for the gramophone sounds relatively primitive, thin and lacking the full resonance of which the piano is capable. These Zenph re-performances, which completely eliminate the technological limitations of the past, use computerised captures of attacks, key-speeds, pitches, durations, plus interpretative nuances including those added by Rachmaninoff’s always subtle pedalling. And all this is done on a 1909 Steinway concert grand in optimum condition such as the composer always played himself.
