Brahms’ connection with the repertoire for two pianos was somewhat delicate. Only two pieces stand out officially in his catalogue – Both on this disc, and both adaptations of other works: The Variations on a theme by Haydn op. 56b and the Sonata op. 34b. Strictly speaking, these versions should not be called “adaptations”, neither from the orchestra nor the quintet op. 34a, for two simple reasons: both predate the final outcome, and both are perfectly suitable for performances, which is their usual use indeed.
