This tattoo is what I would like to call 'The Concert Paradox." Let me explain it to you. You would only tattoo the concerts you've been to on yourself if you really loved music, but if you really loved music, you should be going to too many concerts to tattoo them on yourself. Maybe it's that this person can't afford that many concert tickets, but they certainly can afford to get a tattoo after every single one of them. Just cut out the tattoos and you'd be able to go to twice as many concerts!
That's quite an eclectic mix of bands. What I'd like to know is what happened between 1994 and 2004. Did they have a bad breakup after that Green Day and couldn't bear to leave the house for ten years? Was it the power of Nickelback bring them out of hiding?
