With the 2nd Organ Sonata in A flat major of 1871, we encounter a masterpiece which is already fully formed. The first movement, only loosely related to sonata form in the sense of the title "Fantasie-Sonate", the atmospheric "Adagio espressivo", and the grand finale movement with its fugue and references back to the first movement ensure great success for the grand romantic organ sonata, in spite of its technical demands. Separate edition from Vol. 38 of the "Complete Edition" (Carus 50.238/00). Editor: Martin Weyer
