They seem to be secretly having fun inside a barricaded construction site. I could see a specially made standing ashtray with a folding chair, and even some sort of kitchen facility.
It would be good if there was a gig going on inside. With some special speaker system the beats sound like construction noise from afar but when you get closer you hear “ultra-modern, trance-inducing compositions” (TCF TodaysArt 2016).
