I DJ'd a party last night at a local fraternal order. It's a decent sized building with a restaurant/bar attached to the banquet room. It was midnight when the police showed up to ask me to please turn it down.

He said there was a housing addition 4 blocks away and they were getting complaints. Later the bartender told me that usually only happens when a local rock band plays to a packed house.
Amazing what a 300 watt QSC amp will do when paired with plated T39s fired into the wall. (For some reason guests liked to come back and sit on the musical bench.)
