Quick head's up: I edited the opening post w/ some videos from Larian's YouTube channel. Check 'em out.
I'm so sad to hear about this. For a long time he's been my favourite games music composer, and I've spent so many enjoyable hours listening to his incredibly immersive soundtracks.
A very sad loss indeed.
I know.
I'm pretty damn picky about what music I like, what music I love, and there are very few modern musicians or composers that I really, genuinely adore: Yoko Kanno, Nobuo Uematsu, and Kirill Pokrovsky.
I know Larian re-purposed some older music for Divinity: Original Sin. I hope they continue to do so for future games, because a Divinity game without Kirill's music is no Divinity at all.
