What's the best camera for shooting a concert or music show?

I heard that Point and Shoot camera are good, DSLR also, and Smartphone too including iphone. Q3hd is good too but a lot peoples told that the video quality is not that great compare to an iphone or good smartphone. I want something like I said earlier compact small beacause any venue don't want big pro camera or huge video camera and also like I said with the youtube video exemple I want great audio and video image. I wantpay 500$ or 1000$ when I get a similar quality at a fair and good price for what I need. So what should I get and I know it's on the market today I just have to get it but what?

To be honest if you are going the PHONE route Stick with the higher end Nokia Lumia's or the HTC ONE. Both do a great job compared to Sony and Samsung devices. But for audio quality the Nokia 1020 would be the way to go. It worth investing in the camera grip for the device also

Most concert venues won't allow dslr cameras in because they're considered professional… Copyright laws.
A point and shoot or your phone will work the best.
