Flute- Quartet In D • Adagio And Rondo, Köch. 617 (Glasharmonica-Quintet) • Quartet In D Major • Quintet In E Major

Released by the Czechoslovakian label Supraphon in 1969, this record captures the collaborative precision of the Ars Rediviva ensemble. The album features chamber works by Wolfgang Amadeus Mozart and Johann Christian Bach, highlighting the unique sound of the glass harmonica in Mozart's Adagio and Rondo, Köchel 617. This recording emerged during a period when Supraphon was gaining international acclaim for its high-fidelity captures of classical performances from Eastern Bloc ensembles.

The album reflects the era's dedication to period-informed interpretations of 18th-century compositions. By focusing on the interplay between the flute and string textures, the performance aimed to showcase the lighter, more ornamental side of the Classical repertoire. The record was well-regarded by collectors of the time for its clean production and the technical proficiency of the ensemble, which helped bridge the gap between niche historical research and the broader classical listening audience.
