[1][2] Bruckner has mainly made his name because of his organ playing during his journeys to Nancy, Paris, London and the states of imperial Austria.
With the exception of the later Perger Präludium with its romantic chromaticism, the few organ works date from his earlier lifetime and are mainly based on the baroque tradition.
[3] Only five pieces and two sketches are indubitably autograph compositions:[4] In addition: A few "complete editions" of the organ works have been released.
Franz Haselböck has recorded some of them on harmonium - very interesting as a curiosity, but unfortunately they were not released on CD.
