Here is the famous toccata from Vidor's 5th organ symphony played on one of the monstrous organs of Europe, a Cavaille-Coll in St. Ouen, France. Turn up the sound! Experience the bass! Imagine unleashing such violence by simply tapping on a pedal with your foot. The bass is overwhelming in this recording. I wonder what it is like in person. Perhaps it is more balanced. But can you imagine hearing this sound before there were loudspeakers and electronic sound systems to dull our senses?
