Either that or to either side of the stage if there's enough viewage in between any equipment and crowds. I usually only do that if the back center is too far back

I'd stray away from either of the sides as that would give your recording some pretty bad phasing. The best would be anywhere in the center, though the further you are towards the back, the better your recording will be. It's less of an issue if you've got good recording equipment, but for most people the back is the safest bet.

Thanks
