DESCRIPTION:
I'm a simple man.
I hear something that would go well together, I put them together.
Such is the case with Grimm's two boss themes.

This fucker took me three hours to beat. So good.

The music is by the ever talented Christopher Larkson, who is much more deserving of subscribers than I am, so please give him some: https://www.youtube.com/channel/UCn-mtn6H9BvxVcTRcjMDVhQ
All I did was combine the tracks because damn I knew it'd be good.
Go buy Hollow Knight, too, if you haven't. Fantastic game.
