Sounds from another world so it seems: Sergiu Celibidache conducting Bruckner’s Mass in f-minor.
I will never forget the Benedictus, as I attended a few rehearsals at the time and could witness how it was gradually turned into this miracle performance. Of course one needs the right acoustics for such music, so I recommend earphones for listening to this. Celi’s uncompromising integrity as a musician and the unforced intensity he created are the stuff of legends. Here is the Benedictus from the performance which took place in Linz, Austria. Exceptional.
