Pantera
One of the real constants in my life throughout my early teens and into my early twenties, Pantera occupied a spot of high reverance and admiration in my music life for more than a decade.  I recall seeing the video to "Cowboys from Hell" on Raw Power and losing every last ounce of my shit to it and I recall every track on the debut just blew me the fuck away.  "Vulgar Display of Power" some how took things up another notch or two before the darker and more grimy feel of "Far Beyond Driven" ran through my teenage hormones like a fucking mood hoover!  I read a gig review of a Pantera show and the strap line under the photo just said "Pantera - a fucking heavy metal band!".  But they were more than that even as they bent and wah-wah'd their way into the (frankly awful) title of a Groove metal band.  As with most things that are really good, they didn't last forever and the world being such a horrible place that it is we know we are without two of metal's finest brothers with the sad loss of Dimebag and more recently Vinne, but the legacy lives on.
Key Album - Vulgar Display of Power

You could:
1 - take your dad but have him wear earplugs and a blindfold the whole time. Tell him it's part of the fun.
2 - fly one of us over to pretend we're your dad. Several of us are probably old enough to be your dad, so this could work. Might have to pay us extra depending on who's playing.
3 - show your parents the lineup, and when they say no, freak out. Rip your clothes off, set fire to your hair, throw some blood or feces around, yell "Hail Satan", pretend to have a seizure... something to show them how important it is to you. This should convince them.
4 - scrap the whole thing until you're old enough to go by yourself.
5 - run away from home. Acquire fake ID. Join a traveling circus.
6 - tell them about the show and calmly explain that it would mean a lot to you if you could go, even though you don't necessarily agree with or enjoy all of the bands, because you love the music. 
 
I hope one of these fantastic options winds up working out for you.
 
 
(I should probably also add a disclaimer here: I don't actually advise running away from home and I don't recommend the thing with the fire and blood and feces. Try option 6.)
