Some folks who are really good choose to play fairly simple, straighforward music in their 'working band' incarnations I guess, because that's what pays the bills, and they may actually quite enjoy the genre as well. One that comes to mind is the guy from Guns-n-Roses. I just assumed he was your usual shirtless, tatooed melodic metal type player. But I've since seen him in a number of different situations and the guy is hugely talented and can play all kinds of complex stuff. He just chose to play a specific style for the band that he happened to be in and got well known for.
