It's not an editing trick. I'd bet any amount of money that the drummer's nose didn't look like that in real life. Since that's true, there is a range of photo techniques that can be used that spans between that unrealistic image, and what the scene looked like in real life.
To put it anther way, these photos are not as good as they possibly could be. They definitely could more accurately capture what the light actually looked like. Shooting raw and selecting the camera's native color space will close the gap between this image and what reality looked like.
