Gig's are just like nightclubs. There is usually a slightly better overall vibe at gigs though, more of community, and therefore, people are more open to talking with strangers. You are absolutely correct about the noise! I won't fight that myself. There will be areas where you can hear each other speak, such as in the foyer, the bar, etc.. and between songs and sets. I love those girls that usually set up the radio station tents outside, who ask you dumb questions in order to give free CD's away.
Your limitation here though is that belief. It is a common misconception whenever we see a guy and girl together, most of us think that they are a couple. From my experience that is often NOT the case, even when they seem flirtatious with each other. I can tell with a high degree of accuracy which couples are really a couple, and one where they are very into each other. You can quickly build up a similar level of calibration.. you will have to start talking to mixed sets though to develop this! It is MUCH easier than you think.
If you approach a mixed set like the average guy then you will most likely hurt your chances, and when they are actually a BF and GF the guy might be a jerk to you. Why? ..because you are being blatantly disrespectful, which hurts his ego.
There is a way though that virtually eliminates any possible friction with the guys. In this situation the girl will almost always let you know that they are just friends, or not together. Sometimes the guy will do this if he thinks you are cool, and he has no interest in her sexually. Usually the girl makes a comment about how they are JUST FRIENDS.. or this is my FRIEND Joe.. or she might even say WE'RE NOT TOGETHER. When a girl likes you SHE WILL LET YOU KNOW! Even if she kind of knows that the guy she is with likes her.
So start a casual conversation. Typically start talking with the guy first. Choose a topic or question that he will also find relevant. Then you will quickly discover their dynamic. If not then carry on.. being cool with him, and subtly teasing her, while BEING INTERESTING. Tell a story, say something funny, direct the conversation.. say I'm sorry I'm being rude.. my names..xxxx.. so how do you guys know each other? You can tell from her eye contact, from her laugh, from how long & how she holds your hand, and how she introduces the guy... from those things you can tell the lay of the land.
I often talk to married couples. When they tell me they are married my response seems like I have no interest in his wife, and am just being social. Of course inside I might be saying, "Fuck!" but externally they continue to think I'm cool, and there is no friction. I wouldn't "game" a guys wife, and especially not right in front of him. Many times I totally could.. and I could have her eating out of the palm of my hand... if he's a 'nice guy.' I choose not to. There are many girls.
Have fun at those festivals.. be social.. respect others.. be interesting.. turn on the charm.. listen to them.. you should be fine.
