Why do you think composers can compose in one style only, ever? Also, there is no such thing as "fantasy music", trust me. Music is illusion and sleight of hand. If a composer knows what he's doing, you don't have to worry about it not sounding "fantasy enough".
Well, while I totally agree with you, I think it's a bit unfair to compare video game composers to a musical genius like Shostakovich...
I mean, if somebody is as good as Shostakovich, they usually don't compose for video games. Simple.
What I think is more/most important for the specific case of DOS 2 is that you need somebody who could build upon the specific sound Kirill created for DOS and the whole Divinity series while carefully integrating new ideas. I don't know how many good composers are willing and capable of actually doing so "the right way".
