What camera do i need? - 1

Hi, so i need a camera that is good for when i take pictures in places that are dark or have very little light.
also it should be good without the flash, but with it as well too.
but i would need to use it more without the flash though.
& also preferably a nikon.
thanks

Added (1). It's concert photography, so i can't get a tripod.
price range: $500-$1500

Pretty much any camera works well at night when you have a tripod!

Give us a price range, please. As previously stated, get a tripod.
