Klaviersonaten G-Moll Hob XVI:44, Es-Dur Hob XVI:45, As-Dur Hob XVI:46, D-Dur Hob XVII:D1

Released in 1976 on the East German label ETERNA, this recording of Joseph Haydn's piano sonatas features the pianist Walter Olbertz. The collection reflects the ongoing commitment of ETERNA to documenting the core classical repertoire through the lens of performers central to the GDR's state-supported musical infrastructure. Olbertz was a highly regarded soloist and chamber musician whose interpretations were often praised for their clarity, technical precision, and adherence to the disciplined stylistic rigor expected in the academic music circles of the period.

The design of the sleeve follows the minimalist, austere aesthetic characteristic of ETERNA’s late-period releases. By placing these specific sonatas—Hob. XVI:44 through Hob. XVI:46 and the sonata Hob. XVII:D1—under the ETERNA imprint, the label provided listeners with an accessible, high-fidelity entry point into Haydn's keyboard works. While the record was primarily distributed within the Eastern Bloc, it remains a significant archival example of Olbertz's work and the technical standards maintained by the VEB Deutsche Schallplatten studios during the mid-1970s.
