Four instruments by the Viennese luthier Franz Geissenhof (1753–1821) are featured on this recording by the Austrian-French Quatuor Mosaïques, formed by four musicians of Nikolaus Harnoncourt’s Concentus musicus Wien. The result of this recording of three string quartets by Mozart’s protégé Joseph Woelfl (1773–1812) is fresh and lively, nothing straight from a museum. The extensive booklet gives information on the luthier and the composer.
