As you walk in the park you start to hear music. It sounds like rock music but you can't be sure. As you walk past a few trees you see a concert.
It has a whole bunch of people dancing, talking, and fighting a bit. All of them in various stages of dress. Most of the guys shirtless and showing off muscles or tattoos. But others wearing shirts still sporting tattoos. The girls are all barely dressed in belly shirts or bikini tops. All of them also have tattoos and piercings like the guys.
Then there was a whole mosh pit going on. Pretty much all the moshers were guys and almost all were shirtless.
They are certainly not the crowd you'd hang out with but still. There seemed to be no ticket section, so a concert you could just walk to? That was tempting especially since not that many bands come to your immediate area. Normally you have to drive miles north just to see one.
Your curiosity gets the better of you and you wander over to the concert. No one seems upset that your here for free, so your assumption about it being free must have been correct. Some people give you looks like why is someone like you here? Others looking at you as if they were old friends who were expecting you. Some of them saying things like "yeah man you made it!" Then trying to give you a high five or fist pound. Others saying "hey dude your here" and patting you on the back.
You know for a fact that you don't know anyone here. In fact you've never even seen these people before let alone know them.
Your'e curiosity comes back and you walk through the crowd closer to the stage.
