J.S. Bach - Toccata and Fugue in D minor BWV 565

I love organ music; but you have to listen to it live. The low notes don't come across properly on recorded media (also you don't feel your chest resonate). Bach's Toccata and Fugue in D Minor, one of the most famous pieces of organ music ever, played on an organ built in 1730 (and, if I read the history right, it was actually specified by Bach): [this video] You can hear the recording simply outright fail on the low notes. The organ has a 32-foot pipe, which produces 16Hz notes. The reocrding simply doesn't do it justice; if you ever get the chance, listen to it live; it's an almost transcendent experience. There are, however, apparently two organs in the world with 64-foot pipes (8Hz!) and several more which can synthesise an 8Hz subharmonic using smaller pipes, but I haven't found a recording I trust of it yet.

I agree but I also would remind you that the player plays a large role in keyed music. For example, constant velocity MIDI makes a dissonant slaughter of any harmonic music, and totally destroys the swing of rythymic music. A player with the wrong motivation or lacking passion, pretty much reduces to a souped up MIDI. Organs are especially expressive, even more so than pianos. Try listening to the "Frankenstein music" from Bach, it is pretty easy to relate to and Hans-Andre Stamm plays it on an appropriately large church organ with the necessary emotion and "godhead" existential feeling/motivation behind it.
