Concerts and activities in Warsaw (August)

Hey everyone, just found out that I will be coming back to Warsaw this August and was wondering if there are any good concerts or activities going on around then. I have a flat in Warsaw but, am looking forward to doing a little sight seeing around Poland. So if anything cool is going on please send me a message. Thanks

I guess there always are. Sometimes even some famous bands/people. You could also check the Baltic sea area as in summer there are most concerts there.
