Lagunas Las Salinas?

Anyone know if the earth shaking ear drum piercing noise that apparently passed as music last night down in the Las Salinas area will continue tonight?

It essentially went non stop from 7 pm until beyond 1 pm and could be heard at least two miles away. I tried to sleep with ear plugs and OSHA approved hearing muff with little success.

Is it normal for there to be no reasonable cut off time say 11 pm or midnight to extremely loud and abusive concerts?
