It was the best of times, it was the worst of times. I'm convinced people that like to dress up, always like to dress up. That is, if there is a costume party or some club to belong to, they are first in line to get their gear on. This is always the case with regular concert people.
When I go to a concert, I where whatever I'm wearing. However people at the concert are dressed like they are in Judas Priest. Well for rock and roll shows anyways. I suppose at Lady Gaga shows they are dressed like monsters. Fun I suppose. Not much different than a zombie walk or Rocky Horror Picture Show.
The thing about a concert is it seems most people are going to be seen, rather than to see the concert. Can you really be seen during a concert? Does it really matter? I suppose if you are front row and it is being taped it matters.
Anyways I laugh at concert people. It's good to people watch, and you see people dress like it is Halloween. Everyone tries to be a "rock and roll rebel". The girls hoochie it up, the guys get on their American bad ass routine. It's quite comical and entertaining.
Then of course, you have the "look at my 1979 Journey concert t-shirt I am wearing" folks. Just listen for the sound of the chain wallet walking through the concourse and you'll find them.
