Best pocket camera for a concert?

I own a DSLR that would be great for it, but I don't want to risk getting it taken. I know a great way to hide it getting in, but where I'm up close to the front I'm worried that the security might come take it. Anyway, what is a good camera for indoor concerts? Something I don't have to do much fooling around with different settings to understand it, and obviously good for low light. I know not many cameras are great for this but I did have one before! It was some kind of Canon camera but it broke years ago. So from your experiences, what would be good for this? Size doesn't matter and if it were under $200 that'd be great.

I do have an iphone for a backup but with the band moving and stuff it will most likely go all blurry.

Added (1). EDIT: I have attended classes and all that other stuff for my DSLR but I'm just looking for something half good for a concert. I already know you won't have the most fantastic camera and photos from a pocket camera but like I said, I had one with decent quality before so it is possible. I also did look but couldn't find the answer I wanted.

This question gets asked every single day. If you used the search function (look above, there's a big, green "Search Answers" button), you would have found thousands of answers right away.

First of all, you may not be allowed to bring a camera into the venue, I'd check first.
You might get away with smuggling it in, but personally I hate the possibility that I might either have my camera confiscated, or I won't be allowed inside.
Next problem is that concerts are a low light situation, usually also coupled with much movement as well as a fair distance from the subject.

All up, that makes it EXTREMELY challenging. The only hope of half decent concert photos are good DSLR cameras and even for those you need very good and very FAST lenses.

Small P&S cameras have tiny little sensors, so they don't do well with low light situations.
Concert photos are often blurry because there isn't enough light, so the shutter speed is too slow to hand-hold it, even worse when you add the movement of the performers to it.

You could try raising your ISO, but that will add noise to your photos.
You could try using your little flash, but it can't reach very far, and won't do you a whole lot of good other than lighting up the back of the heads directly in front of you.

I'm afraid there are a number of good reasons why the pro's carry around huge, expensive cameras, lenses, and lights.
It would be lovely if a tiny camera could do it all, but the reality is that small P&S's just can't handle concert situations very well. Some places do allow small P&S cameras (but no DSLRs). The reason for that is because they KNOW you will never get any decent shot with a little P&S.

However, I do realize that some of us a lot easier to please than others, so perhaps what is totally unacceptable to me might be fine in YOUR eyes.
If you can't have a good camera with you, at the very least make sure you learn how to you use what you have, so you can make the most out of it. Read your manual several times, attend a class, read some books on photography - it will help a lot.
If you're not interested in learning much, at the very least learn how to turn off the flash. Those tiny on-camera flashes only reach a few feet, so all you do with it is illuminate the bodies in front of you.

As to sound - there's a good reason why the audio pros carry around a lot of very big and very expensive gear. Even a good camcorder can only do so much in that regard - let alone a little P&S still camera! Don't expect miracles - don't even expect anything you'd ever want to listen to again.

What Selina says is very true. You won't get much better pictures with a compact than on your iphone.
You could maybe take along an Olympus XZ-1 compact with f1.8-f2.5 lens but even though the bright lens will help with with low light the camera will still struggle badly with extreme contrast. Sadly you can't use HDR where the subject is moving about.
