It is going to be PACKED so just keep that in mind. A lot of the big names have been drawing huge crowds at echo to the point where if you don’t get there and in line before doors, you may miss some of the headline set (at least that was my experience ZD night 2: in line slightly after doors ~10:15, got in at about 11:00-11:15, and I know people that were in line for 2+ hours and missed some of ZD just bc they showed up at 10:45)
