For my 14th Birthday, I took 5 of my close friends to a concert. It was a band we all loved (3 Doors Down) and we all had a blast. Before the concert, my mo took us all out to eat, and to go shopping for awesome concert outfits. When we got there, we just hung out and met other fans while waiting for the concert to start (they always are a little late). We met these guys and ended up hanging out and dancing with them all night. I would definitely would recommend this type of party to all teens, but it can be a little expensive, unless the place you see it has a lawn without real seats, then you can get tickets really cheap. The only thing to be cautious of is the older men there, so make sure you walk around in groups. As lame as it may seem, the buddy system works wonders.
