wwhoahwoa a rave or something lol. I told my mom I was going to this convention and apparently there was a rave there.. I didn't know though and some twenty year old asked my friends and I if we were going to come even though we told him our age (I was like 13 at that time..)

Explain her how the concert is ^^ Show her videos and things that will probably convice her... just explain it <3 Fighting~

show her this - http://25.media.tumblr.com/tumblr_mb6cq6wJl41rtvun5o2_250.gif

lol idk I'm no help here...

just be honest and explain it to her calmnly . ^_^

Tell her that you will call her every so often to reassure that you're okay. Also at some stage in your life, you will have to experience a concert, so isn't it better now, when she knows about it?
Reassure her that even if people are getting drunk, you will not be one of those people and that security will be present at all times so the chances of you getting hurt are slim to nil.
Also, if your Mam is holding onto you constantly, when she eventually has to let you go, you will get hurt more then, rather than if she let you go now. You will only bruise more in the future since the cotton wool you were wrapped in wasn't there for you, and you were so used to it.

Hope that the advice was uselful and that your Mam lets you go ^^
Hwaiting <3 ^^

well, since there's going to be so many fans going, #1, there's going to be tight security. and i'm sure there won't be any "rowdy&drunk" people because if they were going to go get drunk, they wouldn't pay for tickets to be at the concert. and so therefore, the closest thing to a fight is like you said:a fanwar. but if it's for a concert, i doubt there will be a fanwar. probably a lot of fangirling though xD
and my mom is super overprotective as well. She let me go to KCON because my friend said she had an extra ticket 2 days before the day, and I got back in one piece even though the fansign was like cavemen who didn't eat dinner or something ㅡㅡ;;
hope these helped! haha.
ohyeah. not sure if the whole "call every two hours" will work, because #1, you won't realize the time flowing, #2 if she calls, you won't hear it, and vibrate doesn't seem to help for me, #3, if she picks up and there's fangirls everywhere I don't think your mom will be very assured .-.

Adding to what the others suggested below, tell her like, you'll call her every two hours during the event or something. If she has that reassurance that you're all right throughout the event, I'm sure she'l let you go. :) That's what I do!

And I TOTALLY agree with cfdorks, to should tell her everything about what your plan is and what the concert would be like. Your mum is just worried for your safety (my mum turned me down when I only asked her if I could 'go to a concert'), so b sure to tell her o keep in touc with you! :)
I'm soooo sorry for the typos, I'm currently on my phone right now ^^;;

(For te Sydney 2011 Kpop Concert) Well...my parents let me go bcos. Was going wit close friends AND my older brothers also went AND the arena was huge so we had extra seats too so I guess I had an advantage. I also sad that I was going to the concert to see the production and see how they put out the concert as experience.
Anyway best of luck! <3

I usually use the tactic where I tell her EVERYTHING I'm going to do.

Like, "If you let me go, I'll be in this area and we'll be here for blah blah and then we'll do blah blah" etc etc. I'm just assuming that you're old enough to go alone and that you have a cell phone on you, so you can tell her that you'll have your phone on you the whole time and that you'll call her whenever you do anything like arriving at the place and etc.

I know it sounds really UGh and annoying to do, but it will show her that you're responsible and that you're aware of your own safety! And if she still says no, just calmly ask her to "give you a chance" to show her that you can do it and be responsible!

hWAITING!!
-eunae

Don't worry! Tell her you know som fiends that have been there and say that it was not rowdy.
If that won't work, convince her by telling that you need a social life and that you know she loves you, but if she loves you, she needs to think about you and how you want to have fun, tell her if she loves you let you go

Have you showed her the website and history of the concert? There's no way it'd be going on for so many years, in a classic place like the hollywood bowl .-.
I hope that you can go; I'm gonna be there~

Ask your father!
