"Sledgehammer" by Lowland Hum

 

Imagine that Peter, Paul, and Mary are time travelling musicians who land in the year 1846.  While following the Oregon Trail from a gig in Independence, Missouri to one in Bear Valley, California, the trio become trapped in an early snowfall near the Sierra Nevada mountain range.  Paul contracts dysentery, and the other two music makers must resort to cannibalism to survive the harsh winter.

I believe that encapsulates the sound that Lowland Hum were gunning for.

Here, they lend their vocal harmonies to Peter Gabriel's "Sledgehammer."
