Symphonic in scale and with great dramatic power, Rachmaninov’s Piano Sonata No. 1 in D minor is an underappreciated masterpiece, depicting a tremendous range of human emotions. The turbulent and brilliant Piano Sonata No. 2 in B flat minor is heard in the 1931 revised version, which clarifies textures and streamlines the work, heightening its emotional impact. The Isle of the Dead employs Georgy Kirkor’s 1957 transcription, which Boris Giltburg has revised significantly. Giltburg’s authority in Rachmaninov has been universally acknowledged, with his performances termed ‘characterful, sensitive, and technically dazzling’ by BBC Music Magazine (Naxos 8.574528).
