Saint-Saens, Symphony No 3 (Organ Symphony), particularly the Barenboim recording where the organ of Chartres Cathedral is magnificent. The Maestoso has been described:
"A great chord on the organ heralds the start of one of the most triumphant moments in the history of music."

This very well-known melody was made into a pop record. I sometimes play it very loud on a Sunday morning, bass full up so the organ shakes the floorboards. Very stirring.
