Here's the information from factorybelt:

The version of "Warfare" on High Atmosphere was done on guitar and vocals by E.C. Ball, who lived in the mountains on the North Carolina/Virginia border. There are a number of compilations of E.C.'s work with his wife Orna, including one on Rounder Records and another on Copper Creek records. It's also been recorded by Sarah Ogan Gunning and Wade Mainer. More recently, it was released in the late '90s by The Freight Hoppers.

I think I have the "High Atmosphere" CD but I can't find it just now. If I recall, the E.C.Ball recording is not particularly easy to understand. Maybe a number of us can work out a transcription.
Be sure to take a look at the factorybelt site.
