Live concert shots are sometimes difficult. Someday I may have to take a few minutes and compose a list of tips to share. But for now: I would wait until the lighting was better ( if the stage guys ever change them ), then catch the performer in a pause ( it helps to know the song ). A singer always has the microphone in the wrong place ( usually in front of his mouth ). Highlights are hard to avoid, especially if the performer is bald or sweating.
I didn't write down all the steps I used in the post-processing, but it was more than one-click fixes. I'm not real familiar with layering so some of this was done with two images and copy-and-pasting. Different areas had to have their own adjustments.
