Winter's Bone is a film that's got a lot of attention recently, a gothic tale which is a wonder of economical film making and note perfect acting. I liked it a lot. It's set in the Ozarks and features a great soundtrack of traditional music. Over at The 9513 is an interview with Marideth Sisco a local singer and folklorist who sings in the movie and helped shape its sound. Really terrific interview not just about her role in the film but the processes of adapting traditional songs for it.

I should note it does contain one spoiler, and it sort of "spoils" a key moment (the moment everyone I've talked to who has also seen the movie has mentioned) so be warned, but it really is a good read.

Update: here is Marideth's personal site.
