Klaviersonaten C-Moll Hob XVI:34, Es-Dur Hob deest, C-Dur Hob XVI:35, Cis-Moll Hob XVI:36

This 1975 release, featuring Walter Olbertz performing a selection of Joseph Haydn's piano sonatas, emerged from the East German classical music scene. Produced during the height of the Deutsche Schallplatten era, these recordings reflect the rigorous tradition of the period's conservatory-trained pianists. The selection of sonatas, ranging from the well-known C-major Hob XVI:35 to the less frequently recorded works, highlights a scholarly approach to the classical repertoire aimed at high-fidelity preservation of the composer's structural integrity.

Walter Olbertz was a distinguished figure in the German Democratic Republic's musical landscape, known for his precision and technical clarity. The design and pressing of this particular release, categorized under the catalog number 8 26 646, followed the minimalist aesthetic common to private or specialized label runs of the mid-1970s. By focusing on the structural nuance of Haydn’s keyboard writing, Olbertz sought to emphasize the transition from the galant style to the more complex developmental structures of the late eighteenth century.
