I have this camera. It has great low light performance.
Here's a sample I shot without flash of a guitarist who was playing and thrashing around. It's surprisingly sharp and has fairly good dynamic range in the contrast and low noise even ISO 3200.
Here's another shot from a recent concert...
This is the perspective from where I was sitting, the above image zoomed and cropped for the result.
At 20MP, it gives good detail even without having a high amount of zoom.
So for still images, this camera is a good choice when you can't get a DLSR into a venue but can get a point and shoot in.
For video, it's a mixed bag. The video is good in 1080p 60fps but the audio is awful. Here's a clip I shot showing how clipped the audio is. Granted, I was right up on the stage monitors so it wasn't an ideal placement for audio recording.

Here's a test I ran versus a Sony PCM-M10 I recently purchased....internal mics here:

It's why I joined this forum and I'm finding a lot of great information on it so far.
