The Louvin Brothers weren't in one of these new-fangled new-age-hippy religions. Hell no, they were part of the old time, hell-fire-and-damnation church. The church of the fightin' Yahweh.
This is their first album, at least that I can find. It is made up of twelve songs of death, redemption, cheatin', lyin', stealin', drinkin', and the fires of hell.
Great cover, by the way. Capitol Records stuck with different variations of this model for pretty much all of their country albums all the way into the early '70s. Don't mess with success, I guess.
