Red Headed Stranger by Willie Nelson

A western tale about a man who finds his wife cheating on him, kills her and her lover, then later finds love and redemption. Very unique for a concept album because it uses both original songs and covers to tell the story. The album’s artwork included a storyboard of the tale. Maybe not the most original story idea for a movie or a song, but for an album it was groundbreaking. Considered one of the greatest country & western albums of all time, and they even made it into a movie.
