Tricky. It is a very dark image and what is lit up shows as shaky and noisy. Let's make art rather than excuses though - here is what I came up with:
I took a copy of the brighter image of the singer, used the perspective tool to reduce the angle distortion and increased it in size. I then set this as a new layer and put it in screen mode, cropping to remove some of the other elements. This makes it look as if the other images are reflected in a large screen. I then added another layer and filled it with a blue to purple diagonal gradient (picked from colours in the image) and set that to hard light mode (blending the opacity down to taste).
I don't think the result is astounding but it makes the singer much more the focus of the image.
