This new publication offers a source-critical edition of Mozart’s fragmentary “Requiem” (Bärenreiter-Verlag) as well as an alternative to the traditional Süßmayr version. When completing the fragment, the editor Michael Ostrzyga drew on comprehensive comparative and analytical studies of Mozart’s church style and compositional workmanship. The influence of Handel and Bach manifested in his final years, particularly in the “Requiem” fragment, is taken into account in those sections requiring completion or fresh composition. At two points readers may choose between alternative movements (or sections), since proceeding from Süßmayr’s historical version, two divergent options cannot be weighed against each other but each one may well reflect Mozart’s intentions. The new completion offers choirs and orchestras the opportunity to perform this legendary work in a well thought through version based on the most up-to-date research.

To celebrate the 200th birthday of the Norwegian playwright Ludvig Holberg in 1884 Edvard Grieg was commissioned to write an open-air cantata for the ceremony. But he also refers to Holberg in his instrumental music. The result was a “powdered wig piece” (as Grieg wrote to his publisher) that hearkens back to Holberg’s era – a historicising suite of baroque dances for piano, ranging from an exhilarating prelude and several dance numbers to a Bachian “air” and an impetuous “rigaudon”. Later Grieg arranged his suite for string orchestra. This version became one of his most popular compositions. For the new scholarly-critical Urtext edition (Bärenreiter-Verlag) Christoph Rinne-Schroeder has meticulously examined the original print and compared it with previously neglected performance material annotated by Grieg himself.

The impact of Christoph Willibald Gluck’s operas, which cannot be over-estimated, is generally well-known. A series with four albums, arranged by vocal range, now makes his arias available for teaching and performance.
