Philistine: Mahler's Symphony of a Thousand.

The 8th Symphony is a monumental work, involving the full orchestra, three choirs and eight soloists, plus the organ and a harmonium. The harmonium was off-stage, supposedly to tmper its sound a bit, but really because the packed musicians needed a bit more room than the middle seat in economy class. We are talking about 500 bodies on the stage, and that they all were there on time is just a feat in itself.
