I shot a friends band at a restaurant and have a few questions.
It was not ideal lighting, but I think overall it was 'ok' for an inside patio with little light around.
My 7d Mark II wanted to go to 12800 Iso all night long, because I had it on auto iso and the lack of light. I shot in RAW.
I shot most of the pics in Manual, 2.8, 1/200-320 ss, center-weighted metering, auto iso and auto wb.
I would then set my iso to 6400 or even 3200, but the pics were VERY dark on the lcd screen.
Maybe I shouldn't put too much weight on the lcd screen? I looked at the histogram and it didn't help as everything was way too the left.
Not sure if the high iso is common in these situations or maybe I have accidentally set something that I don't remember doing that's 'asking' the camera to go that high. I can manually set the iso or set the range, but maybe I did something else, not sure...
This picture below was taken at 55 mm in manual mode, 2.8, 1/200 ss, iso 12800. My lens is EF-S 17-55 2.8 is, usm.
I lightened it up in lightroom, a lot, and reduced the noise, a lot. In the background there is a nice big blue/red Lite Beer sign as you can see the blue lights in the upper left corner.
Black and white is ok for some of these photos, but the color is a challenge for me.
Also, this musician loves to bounce, bend, and move around, so straighten the pictures is also a challenge as nothing in the background is straight. The bricks aren't nor is the banner, haha....
Your opinion, does it look ok?
It's just for him, his band and his family. I did it for fun, because I like the music and he's a friend.
Nice shot. It really is. 
Nice work in post, especially.

Sometimes it helps to know how much DOF you're goint to have ahed of time. I always look this over when selecting a lens to use for a given scenario.. At a distance of 10 feet, you should have had just over one foot.
Under low light conditions, I will sometimes underexpose by 1-3 stops, just to get a higher shutter speed, and correct it in post.
OK shot especially for conditions.
The only one that needs to say so is the person that you are supplying it to. BTW, if the blue bothers you that too is easily correctable in post.
My personal routine is to do lens correction upon import in LR. Then set the detail to 1.0 and about 25 or 30. Less is usually more there. Otherwise you get the super contrasty photos some guys try to pass off as nailed focus and IQ.
Lastly, I do the over correction like cropping and fixing the blue area if warranted. Whatever other stuff it needs.
