Given his notoriously temperamental nature, his hatred for filmed or televised concerts and the less-than-welcoming stage settings he insists on performing in, capturing this 1989 performance by pianist Sviatoslav Richter was a near-Herculean feat. Recorded at London's Barbican Centre, selections include Wolfgang Amadeus Mozart's Piano Sonata no. 4 in E-flat Major and Frédéric Chopin's Etudes, op. 25, nos. 5, 6, 8 and 11.
