Vol. 4 in Barry Douglas’s monumental, well-regarded solo piano Brahms project prominently features the composer’s first published work, his C major Sonata, op. 1.The influence on Brahms of his predecessors Beethoven and Schubert is obvious, not only in the virtuoso demands on the performer but also in the opening, which recalls both Beethoven’s ‘Hammerklavier’ Sonata and Schubert’s ‘Wanderer’ Fantasy.Two other impeccable and impressive works, the Schumann Variations, op. 9, and the Paganini Variations, Op. 35 (Book 1) are included, along with several short keyboard character pieces.
