The message
from "Franz Heymann" contains these words:

It would be much more fun to torture the neighbour.
Messiaen composed some organ music whuch is totally
cacophonous. The music becomes even more strident and
formless if you are in a position to play it through a setup
which allows you to switch off the woofer speaker.. The
occupiers of a certain nearby house was in the habit of
playing moronic pop loudly in their garden, until I started
annoying them by playing Messiaen organ music in mine even
more loudly, as organ music should be played.

Try Le Merle Noir - with a flute shrieked by Zdenek Brudehans.....

(Bit of a tautology, Merle Noir.....)

And if you want any volume of an orgy of organ, see if you can get a
recording of Havergal Brian's Gothic Symphony - scored for (IIRC) triple
organ and double orchestra.....
