• Poland-born US emigrée Wanda Landowska (1879 - 1959) was the first to record Bach’s Goldberg Variations on harpsichord and was a lifelong scholar and performer of Bach’s keyboard works.

• England-born Dame Myra Hess’s (1890 - 1965) performances remain peerless for their lucidity and sheer musicality. As a Jewish musician, she played Bach and other German composers in blacked-out venues during the Nazi’s bombardments on London.

• US-born Rosalyn Tureck (1913 - 2003), who Glenn Gould called his “only influence”, helps listeners rediscovering Bach in every piece.

• Martha Argerich (born 1941) brings Argentine temperament to her forceful but extremely articulated playing, using the piano for what it is: a percussion instrument.

• Maria João Pires (born 1944), perhaps better known for her Mozart, Schubert and Chopin, brings a peerless sensibility and depth of sound to her Bach and continues to give masterclasses in her retirement.

• Canadian pianist Angela Hewitt (born 1958) creates a unique sound in her Bach world, playing with extreme integrity.

Are yesterday’s musicians and composers today’s coders?
