Strongly encourage people to hear a big pipe organ at least once, like the Wanamaker in Philadelphia. Church ones are usually great because of the acoustics. It is a visceral pleasure like no other. No matter how good your home sound system is, it won’t compare to the chest-rattling and wholly immersive in-person experience.
I accidentally ended up in a church while the organist was practicing. It felt like the whole building shook, which is impressive in a 500 year old building with meter thick walls.
I can totally see how people used to think pipe organs were the voice of god.
