Fantasia and Fugue in D minor Op. 135b Breitkopf Urtext edited by Hans Haselböck, Hans Klotz and Martin Weyer un-shortened version based on the autographe - Breitkopf Urtext on the basis of the Reger Complete Edition ed. by Hans Klotz, critically examined by Martin Weyer with an introduction by Hans Haselböck This separate edition is particularly noteworthy since it presents Reger's last significant organ work in its entirety Except for the Reger Complete Edition, this work has been published heretofore only in a radically shortened version, which apparently reflects Reger's last wishes, but does not allow a satisfactory appreciation of the creative process. Precisely in its original, completeform, this key work, dedicated to Richard Strauss, Shows that Max Reger underwent a period of radial stylistic change towards 1915, the development of which was hindered by his sudden death.
