I remember when I was slightly younger getting a good t-shirt of a band I liked meant the world to me but gradually its become less and less of a necessity to pick one up at a gig to the point I almost never do now. so in the interests of nostalgia..

I used to have a Fishbone one that I was really proud of, and I have a nice Pixies one.
this is my favourite though, maybe just because i actually got it at a show but mostly because the design is killer
