I've experienced this a couple of times. The events don't go on late at all but the level of noise is truly excessive. I actually don't mind the volume but the bass or reverberations, whatever you call it is so invasive it was making glasses in my house rattle and shake. After a couple of hours the constant vibration was actually making me feel sick - it felt like turbulence or motion sickness. I did look up the number for noise complaints but thing is, every so often it would go quiet for about 15 minutes so I didn't call, then just when you thought they were done, it started up again..
