Easy. First, get off f/16. Nobody needs that much depth of field and diffraction at a concert. In low light, you gotta make f-stop your friend. Open to f/4, or f/2.8 and put another 5 or 6 stops of light on the sensor.
Next, get off 1/1000. It's a concert not game 7 of the Stanley Cup Finals. Slow to 1/250 and put a couple more stops of light on the sensor.
I have no idea what "settings effect" is. That means you can ignore it.
I've just put 7-8 additional stops of light on the sensor. That low light situation isn't so "impossible" anymore. The EVF view is much better. Adjust ISO (image lightness) until the EVF view is pleasing to your eye.
In photography, it's important to adapt to the situation. You may arrive at the Billy Idol concert wanting to be at f/16, 1/1000. (which blockhead suggested those settings for this show?) But when you see the low light level (Billy doesn't like to show off the wrinkles) ya gotta alter the gameplan. Inflexibility is a cardinal sin in any creative endeavor.
Don't fight the conditions; work with them. Embrace a shallower depth of field or a wider angle of view. Embrace a slower shutter speed and the motion blur that may come with it. In fact, after shooting the first set at 1/250, I'd slow to 1/60 or 1/30 and have some real fun with motion blur...while putting another 2-3 stops of light on the sensor.
It's all about the light.
Finally, you're a beginning photographer and you're going to make mistakes. Most of the photos you come home with are gonna suck. Most of the photos I come home with, suck. But it's the handful of good to great shots that make a shoot. That's the target. If you come home with one great shot, that's a great day. Five is amazing. Ten or more is literally a miracle :)
Embrace the mistakes and the sucky photos. That's how we learn. It's proof we're pushing the creative envelope. And when it delivers, the results of that approach are fantastic.
Have fun at the concert.
