not sure if you've seen this video but it's def making the rounds on social media. it's one of the world's first "vertical concerts" that happened in Kiev, Ukraine.
the clip is from a show by Ukranian rock group O.Torvald and they played on a rooftop which was positioned opposite of a hotel. The audience was people on the balconies in the hotel rooms!
all im sayin is this could be the next step after drive-in concerts perhaps?? check out the video below-
