Hi Ess Jay! That sounds like an awesome event!! I would imagine it would be more like a house party where you don’t have a traditional dance floor to dictate what you play. This is pretty fun because it really allows you to be creative with your mixes without having to worry about killing the floor. I guess if it were me I would focus on high energy tracks and try to capture feelings that go with free running/ parkour. I like your idea of playing 5 or so tracks per genre, but of course you’ll want to adjust based on what kind of reaction you’re getting from the crowd. In this case it sounds more like you will be in charge of the “feel” for the event, rather than a dance floor so I think the strength here would be in your track selection. Good luck with this event, it sounds like it will be a blast!
