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 1971, this recording features the Ars Rediviva Ensemble, a chamber group renowned for their commitment to historically informed performance practices during the mid-20th century. The album serves as a curated exploration of late 18th-century chamber music, pairing Mozart’s Adagio and Rondo for glass harmonica, flute, oboe, viola, and cello with works by Johann Christian Bach. It reflects the era's growing scholarly interest in the specific instrumentation of the Classical period, particularly the ethereal, haunting timbre of the glass harmonica.

The design of this release adheres to the clean, academic aesthetic characteristic of Supraphon’s chamber music series from the 1970s. By prioritizing clarity and technical precision, the Ars Rediviva Ensemble sought to bridge the gap between archival research and modern listening, positioning the record as both a musical performance and a pedagogical document. Upon its release, the record was well-received by aficionados of period-correct chamber music for its delicate balance and the ensemble's dedication to the unique sonic requirements of the glass harmonica repertoire.
