ITT: good compilation albums

Smithsonian's Folkways has a bunch of other cool compilations although you're not going to find anything that's as good of an all around collection as the Anthology of American Folk Music. It can be fun to dig through their different albums because they've got all sorts of stuff and nearly every sort of traditional ethnic music, https://folkways.si.edu/

Sounds of the South is a great compilation focused on traditional southern music. There are a few traditional black church preacher tracks too, the one called "Sermon Fragment" was sampled by Kanye on New God Flow.
