Op. 131d-The rediscovery of the original manuscripts of Max Reger's works for violin viola and cello op. 131a-d represents a minor sensation. These late works for solo strings dating from 1914 and 1915 the last of which was only published posthumously were only known from the first printed editions until now and a scholarly-critical edition based on all the sources has long been desirable. The new edition from the Max-Reger-Institut now fills this gap.
