Bands are generally done by 10pm at the latest and there aren't very many of them these days.
I would keep an eye on Paradise Club and Myett's FaceBook pages for parties on the nights you are here. This Friday is a holiday so expect this weekend to have some noise on Friday and Saturday. If you come in 10 days, it will be during the week and should be quiet.
I was on the beach at 9pm last night and everything was quiet or closed.
