Aries: Will probably break someone's neck when someone spill their food or hit them accidentally

Taurus: Will be the only one who was eating a bag of chips for the rest of the show, finishing it at the exact time the show ends

Gemini: Will be the one who keeps on screaming their lungs off

Cancer: The one who is quiet the whole time, videoing everything, and singing softly but will scream when something exciting goes on

Virgo: The one who keeps an eye out for their friends whilst enjoying the show

Leo: Will be the one who keeps on taking selfies, photos, videos, etc. and posting it on social media for hundreds of time

Libra: The one who keeps the enjoyment in theirselves, the one who is peaceful the whole time

Scorpio: The one who throws stuff on stage, hitting the artist accidentally or trying to get attention

Sagittarius: Will be the one who will dance wildly to the music. May or may not look like an animal while dancing but just so carefree. Will not care when someone will tell them off

Capricorn: The one who will scream the lyrics of the song. Will also be the one who will try to get the attention of the artist without throwing things

Aquarius: It depends on the situation. If he/she feels like it's the best moment of their life, they will probably cry from too much happiness. It's very rare to see an Aquarius cry but it is a special occasion whenever they go to concerts, watching their favorite artist/s perform. Or, they will probably act normal.

Pisces: The one who cries the entire show from too much happiness. Will also be the one who will overreact  when something happen to the artist.

Okay guys, this is from personal experience. Or what I think they would do. Please leave suggestions and please comment if your sign doesn't receive too much spotlight. Or if you think your sign will never do that.

I will see you again, fellow human beings.
