I found an old concert t-shirt from a concert I went too in highschool.
Cool! What style of music? 
Deftones. They're an "alt metal" band
Ah I've heard of them, they used to be played on some of the local rock stations. Love a tour t-shirt, always means you might make a friend if you wear it out as other fans are bound to compliment you!
Yeah, I haven't listened to them in years.
