Here is the Anton Bruckner Organ, located in the Alter Dom of Linz. It was built by Franz Xaver Krismann and Bruckner served as the organist from 1856 to 1868. The church was built from 1669 to 1678. I went to a recital given by the current organist, August Humer, who also happens to be my teacher. The organ has some amazing sounds, and the acoustics, while not quite as live as the new cathedral, are still phenomenal (4 to 5 secs). Last Sunday a Mozart mass was performed by a chamber orchestra and choir and it was just enthralling. I alternated between tears and goose bumps the entire time.
