The videos were amazing and the lighting was perfect . Every single song they played they played 110 % , all of them are superb musicians , they pull off some crazy stuff , musically speaking , a lot of weird changes and strange tempos , the crowd was digging it . The one thing that surprised me was from end to end of the venue , it was a sweaty mess of a dance party ; for sure , everyone was going nuts .
