Klaviersonaten: D-Dur, Kv 284 "Dürnitz-Sonate" / B-Dur, Kv 333 / C-Dur, Kv 279

This recording was released in 1967 as part of Ingrid Haebler’s ambitious cycle of Mozart’s complete piano sonatas for the Philips label. Haebler, an Austrian pianist renowned for her refined, historically informed approach to the Classical repertoire, recorded these works during a period when Philips was establishing its reputation for high-fidelity classical releases. The Dürnitz-Sonate, K. 284, along with the K. 333 and K. 279 sonatas, served to showcase her delicate touch and nuanced phrasing, which favored clarity and structural balance over the more overtly virtuosic interpretations popular during the mid-20th century.

The design of the Philips 'Hi-Fi Stereo' era sleeves from this period was characterized by a minimalist, academic aesthetic, often featuring crisp typography and understated portraiture. Haebler's cycle was critically well-received for its consistent scholarly integrity and gentle elegance. By focusing on the inner voices of Mozart’s writing, Haebler helped solidify the expectations for a 'Mozartian' sound—one that prizes lightness and tonal transparency—a standard that remains influential among listeners and critics who appreciate the stylistic continuity she brought to these recordings.
