capturing a live concert?

i have a camera phone which is the Nokia N8 - whenever i'm watching concert - I'm capturing the band performance using my Nokia and it's superb. I'm wondering if which from the two models will provide me best recording a closed door concert - the one that will capture the stage lights - the darkness and efects as well as the good quality of sounds. Im looking for clarity of video recording (images and sounds) clear outdoor picture, battery life
