Wolfgang Brunner presents two opus numbers composed by Dussek in 1792 and 1800, around the time of the beginning and then the painful end of his marriage to the singer and harpist Sophia Corri. The comparatively early Op.18 No.2 shares the modest dimensions of Haydn's early keyboard sonatas, though by then Dussek was 32 years old and Haydn had already paid fulsome tribute to the younger man's 'remarkable talents'. Upon his marriage to Sophia he ran a moderately successful music publishing firm with his new father-in-law, Domenico Corri, but when the firm went bust late in 1799 Dussek abandoned Sophia and their daughter and fled to Hamburg; during the following year he wrote a trio of sonatas published in 1802 as Op.45. These are all more ambitious in scale and expressive reach. The slow movement of Op.45 No.1 bears the significant marking of Adagio patetico, and it explores reaches of grave feeling through harmonies in advance of their time. The two-movement Op.45 No.2 opens with a Larghetto sostenuto of grave concentration, though the mood is lifted by a gently circular, almost Schubertian Andantino. A lighter, more cheerful character pervades the D major Sonata Op.45 No.3, which concludes with one of the effervescent Rondos for which Dussek was celebrated in his own lifetime. On this recording Wolfgang Brunner plays a pair of instruments from Dussek's time: an 1804 Broadwood, and a modern copy of a Viennese fortepiano originally made around 1810 by Michael Rosenberger. Once complete, the cycle will form the first-ever recording of Dussek's sonatas on historically appropriate instruments.
