i used to go to nothing alone, but lately i've been going to stuff by myself, yeah. i miss a good majority of the shows i wanna go to around here because i'm not allowed to go to at least 9:30 or black cat alone, but that does not mean it does not happen.
i don't mind going to shows in DC alone since i always run into someone i know.
but usually, when i end up going to something by myself, it is because i have a friend in the band or whatever who has begged me to come and they're either visiting from out of town or i need to go see them for some reason and i go.
THIS IS A TRAP.
well, it can be really good sometimes, but there is always too much down time. if you end up going and not knowing anyone at the show...i always find myself sitting on some chair or couch or barstool, alone, waiting for them to play, or waiting for them to finish warming up, or waiting for them to finish soundchecking, or whatever. and it doesn't even make a difference if you are sitting backstage or sitting in the back of the club. your friends are almost always busy, and it just gets really tired sometimes.
i end up going to stuff by myself in LA a lot, which is always fine, because everyone in LA is always very friendly. Philly people are also great. and i went to a show by myself in New York which was bad. i was, again, waiting for my friends to play, and they kept coming in and out to hang out but all this other crap was going on. i sat/walked around waiting for people to come talk to me and texting and no one else really did...i got a very evil hipster vibe, which wasn't cool.
so going alone can be pretty lonely and LAME but can also be okay if you make friends or run into them. and, sometimes, a bad idea if you have trust issues.
