When I shot concerts a few years ago, I always found the red channel to be the biggest problem...for some reason, lighting guys seem to LOVE red stage lights.
If the stage has older can lighting with gels over the lights, you'll want to push your WB towards incandescent. Also, if you use flash, be sure to gel it CTO and dial the EC down a stop or two to balance. I never really liked using flash, but some places have insanely dark stages and it was necessary at times.
For LED lighting, you're going to need to watch your color channels in your histogram as you are shooting. If all they have on are blue LEDs, your red and green channel will be almost empty. If you overexpose the blue channel, you'll end up with plastic looking skin tones. I found setting Vibrance to -25ish would recover some detail for slightly overexposed shots.
As far as camera profiles, I would start with Canon Neutral, as I found the Adobe profile exacerbated the problems with the red channel. Beyond that though, I'd have a handful of presets in LR to quickly apply common corrections I found myself using repeatedly, but due to the nature of concert photography and the variety if venues I shot in, there wasn't a common profile I could apply that made sense for most of the shots. Shows ended up needing a lot of individual editing, unfortunately.
