Is it a bad idea for me to go to a concert by myself?

I'm a 16 year old girl, I am pretty self reliant and my city is pretty small. My parents have no objections and I know a few people who are going too I just don't know if I can chill with them because of the fact that I am not super close to any of the friend groups. It's Rise Against and Flogging Molly and I was likely going to get floor tickets, is this too risky?
