Shostakovich was so impressed with Tatiana Nikolayeva's playing at a Bach festival in Leipzig in 1950 that he started writing preludes and fugues for her, and although he hadn't necessarily intended to compose a full set, his 24 Preludes and Fugues Opus 87 was complete within a year. She was the first to play the complete set in public, in 1952, and the first to record them, in 1962. She recorded the set twice more, in Russia in 1987 and in London in 1990, but the first set was always rumoured to be the best, and it has never been available in the west in any format. So, a real rarity for your delectation.
