im turning 21 next month (yay!) and i currently go to a ton of the 18+ events, shows, festivals, etc.. but theres one of the top nightclubs in my city (foundation nightclub in seattle, if anyone knows) and its 100% EDM music, so im really excited for that, they have pretty famous DJ's do shows there just about every weekend and im just wondering if the vibe there is gonna be the same as the festivals and shows i go to that are 18+? because at those shows 99% of the people are rolling, is it the same concept at clubs? or is the majority just drinking?
