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

Released in 1969 by the Czechoslovak label Supraphon, this recording features the Ars Rediviva Ensemble performing a selection of Mozart’s chamber works, including the Adagio and Rondo for glass harmonica, flute, oboe, viola, and cello. The album emerged during a period of high international regard for the ensemble, which was founded by flutist Milan Munclinger. The recording is notable for its inclusion of the glass harmonica, an ethereal instrument invented by Benjamin Franklin that rarely appears in standard chamber music repertoire, highlighting the label's commitment to documenting specialized classical performances.

The album's design and curation reflect the mid-century Eastern European approach to classical music presentation, prioritizing clear, academic annotation and authentic period-style instrumentation. Munclinger and his ensemble were widely respected for their meticulous research into Baroque and early Classical performance practices. By pairing Mozart’s quintets with works by Johann Christian Bach, the release sought to contextualize Mozart’s stylistic development within the broader influence of the Bach family, receiving positive notice from critics for the ensemble's precision and delicate tonal balance.
