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

Released in 1970 on the Czechoslovakian Supraphon label, this recording features the Ars Rediviva Ensemble, an influential Prague-based chamber group founded in 1951. The ensemble was widely respected for its commitment to historically informed performance practices during the mid-20th century, often utilizing period-appropriate instrumentation to breathe new life into Baroque and early Classical repertoire.

The album pairs Mozart's K. 617, famously composed for the glass harmonica—an ethereal instrument invented by Benjamin Franklin—with chamber works by Johann Christian Bach. The production reflects the aesthetic sensibilities of Supraphon’s long-standing series dedicated to preserving European classical tradition, favoring balanced soundscapes and clear, scholarly fidelity that highlights the delicate, crystalline qualities of the glass harmonica against the strings.
