Well, my first discovery on my 1001 project has got to be The Louvin Brothers. This album from the 50s is amazing – although I would have posted it here just because of the cover... My first reaction was to laugh at the lyrics but it's pretty heartfelt stuff from two god-fearing men. A big inflence on later Byrds albums, particularly Sweet Heart of the Rodeo which features a cover of one of the tracks on here. The Louvin Brothers – Satan Is Real
