Over the years Lollapalooza has turned into  a very chaotic environment. Hundreds of under 18 attendees turn violent and illegally drink alcohol that they cannot even handle themselves. Over the years there has been increase of uncessesary fights and violent acts that has ruined the experience for the rest of the attendes. Immature people cannot handle a festival. They do not deserve the right to be there if they cannot act right. Social medias has backlashed and commented on this too. Anything they choose to do at the concert will be their own responsibility and nobody else's. It's smart from a company's perspective because they avoid the possibility of someone underage getting hurt in any way, in which case a parent or guardian would have to be contacted which may in turn result in legal troubles. As a fan, I personally would rather an event be open to 18 or 21 year olds people because kids are more likely to do something irrational and stupid, putting the venue at risk of having to be shut down as a result of an adolescent's poor behavior.
