This is something that's been a question of mine since I started listening to live recordings of bands: why don't you hear the pyrotechnics on the recording? On officially released recordings, ok, there are good reasons for every band this side of KISS to edit the bangs out, but even on bootleg tapes made with handheld recorders, the explosions rarely register. With as loud as those things are, I'd expect them to cause massive distortion--so why don't they show up at all most of the time?
