For example:

https://soundcloud.com/experimedia/chris-watson-el-tren-fantasma (you can hear on the fourth segment that he's actually edited the music into a rhythm.

Combined with Lomax type vocals (but not sampled, just recorded primitively).

Here's an example of something that approaches what I'm talking about, but doesn't quite work, although I still find it enjoyable (while others find it an embarrassing mess):

The link you had kind of has the opposite effect of what I'm looking for. They're taking field recordings and dragging them into the modern age, where I want the modern stuff (rapping) dragged back into the field recording age.

This is also a recent example of something that approaches what I'm thinking of, too. I'm not necessarily looking for something this absolutely stripped down and real time, but I like the philosophy of it, and the fact that it's a skilled rapper doing it.
