Each of these two instrumentalists has a highly successful solo career; together, however, they maintain a violin/piano duo that fascinates listeners with meticulously worked-out, highly intense interpretations. For their first album together, Mirijam Contzen and Herbert Schuch have selected works of composers who resided in 19th century Vienna. Schubert, Brahms and Zemlinsky represent three different generations of Viennese musical life, each with its own distinctive character. Schubert’s great C Major Fantasie is hardly ever heard in as concentrated and masterful a version; seldom is the work’s musical substance formulated as urgently as by this duo, which plays so well together. Zemlinsky’s charming, early “Serenade” is a true rarity of the chamber music repertoire, and certainly unknown by most listeners.
