The name Siegfried Mauser may not be familiar to Western European ears, but those who do know the name know him as a pianist who has specialised in 20th century German contrapuntal pianism from the likes of Hindemith, Hartmann and Henze. Now is probably the optimum time for him to be investigating Mozart’s keyboard sonatas as he has also published a text on them and has recently been made head of the Salzburg’s esteemed Mozarteum.

Of course there have been many surveys of this cycle and it often comes down to personal favourites. Mine include the straightforward approach of the 50s’ EMI cycle by Walter Gieseking. For modern cycles, I’ve long been an advocate of Mitsuko Uchida’s fine Philips traversal. Frustrating and amusing by turn, I’ve also been fascinated by Glenn Gould (Sony), where critics have gone so far as to suggest that this must rank amongst the worst discs ever made! Yet somehow in spite of his distortions, Mozart’s music survives and encourages debate, and surely this is important.

Against this backdrop Mauser may appear as coy if not conservative, for he is completely at ease in letting this music speak on its own behalf. And surely the fact that he has recorded the cycle and written an academic analysis of it makes these works pertinent equally for today’s performer and listener alike. As well as presenting all of Mozart’s sonatas here, there is also a generous selection of late solo works.
