This documentary is about the life and works of the Austrian composer Anton Bruckner, a world-famous organist, a beloved teacher, and a controversial composer who in some ways serves as a biographical puzzle piece linking Wagner and Mahler (among many many others). It contains many musical excerpts (two of them from performances not published in any other form), numerous portrait photographs, drawings, silhouettes, written materials, quotes from Bruckner's and others' diaries and other media.
