Sergiu Celibidache conducts Anton Bruckner's Mass in F-minor, which Bruckner called "the most difficult of all masses". A documentary from the orchestra’s first raw rehearsal to the elaborate concert in the Baroque church of St. Florian where Bruckner once played the organ and now is buried.
The film documents the work process from the first rehearsals with piano and choir to the eventual integration of choir, orchestra and soloists. The musical structure, initially created in Munich, is adapted to the acoustic requirements of St. Florian, and then performed in concert.
