Jannus Live hosts this free concert for ages 21 and older.
NOTE: You must have a ticket AND arrive early on the day of the show to enter, however. Organizers are clear that you can't show up an hour before the gates open and expect to get in; they're also distributing more tickets than the capacity of the venue, which is why having a ticket doesn't guarantee admission.
There are several ticket drops in the days leading to the concert. Get a schedule of locations here.
