Melancholic, dark Bluegrass?

I love bluegrass but really really into the slow paced, darkish, melancholy but oddly soothing stuff that gives off a dark rainy evening kinda vibe. But i can't seem to find any, a few that I have found are

Crooked still - Ecstasy (instrumental edit)

Mad Lasso - Missouri (don't know if this is considered bluegrass or country but easily one of my favorite songs of all time)
