But I'll wait and see how I feel next Tuesday.
Concert t-shirts and band t-shirts are a tricky fig. I own a lot of them, I like to buy them, but I usually gravitate towards the ones that don't look like a band t-shirt. You walk down the street with a t-shirt with the bands name in big letters (or worse, with the tour dates listed on the back) and you're giving a lot of information out to anyone who walks by. Everyone who sees you automatically knows one thing about you. For better or for worse, I suppose, but usually it's not a good thing. I like to maintain a bit of mystery about myself to strangers.
So I pick band shirts that you at least have to look at for a second to see what it is. Ideally, it's a cool design that doesn't make the band name prominent at all. Furthermore, if they ever drop way out of vogue or you no longer want to imply that you're a big enough fan to parade around as a walking billboard, you can still get away with wearing the shirt without implying all that.
The trailers for the new Transformers movie show Shia Lebouf running around in a "Is This It" era Strokes shirt. You can take a lot about that character looking at that shirt. It's an effective tool to frame movie characters, because you only have 2 hours or so to get this guy across. Put someone in a Strokes shirt and it says something about the character. Put them in a Metallica shirt and it says something else. Put them in a Blood Brothers shirt? It says something interesting. But nobody would get it. Not for this movie, at least.
Anyway, point is, I don't want to show off. I'd rather the people who quietly pass me on the street not think of me at all.
