Universal Hollywood Summer 2017 Dance Jam?

[Jerroddragon]

Hey guys so going to the park this Friday when the new Characters debut at the Hollywood park, but in the Youtube video they say something about a Dance Jam. Any idea when this starts and what it is? Is it like DCA where they have a DJ and play music? Or maybe just music playing?

Thanks for any information, we asked the Guest Relations people about this last week and they had no idea so just wanted to see if anyone here knew. Thanks
