The combat music in Vallaki Northeastern Grove, seems far too dramatic for a peaceful area so close to the town. There isn't any danger, or spawn locations (as far as I am aware) nore does there seem to be any secret passage to any menacing area, but when you attack the squirrels for pelts, it sounds as if your assaulting Castle Ravenloft, something a bit more default, would probably be the best choice for combat in this area.
Also in the Eastern Farmlands, with the farms and the workers chopping wood, some sounds around the surrounding farms of chopping and sawing wood, would enhance the area.
