The Great Divide - The Cardigans (Mad Men, Season 1, Episode 2)

"With so many armchair historians in the audience, juxtaposing untimely music against a carefully painted 1960s backdrop is risky business. But it's also an incredibly effective way for Mad Men's writers to say that what's happening on screen is so important that they've got to risk everything expected of them to make a point. Here's a look at the most compelling musical anachronisms in the series so far and how the show used them to emphasize important moments:

"The Great Divide" by the Cardigans 
Season 1, Episode 2: "Ladies Room"

The first time a musical anachronism disrupts the show's historically accurate rhythm comes at the end of the second episode in the first season. Don has just spoken with Betty's new psychiatrist, who helps the adman realize he's more emotionally disconnected from his wife than he thought. As Don closes the door of his study to speak further to the doctor, the Swedish alternative rock band's 1996 music box ballad creeps through the Drapers' seemingly perfect 1960's home. A white double oven comes into view before fading quickly.

The Cardigans' "The Great Divide" is, of course, about division, describing "a monster growing in our heads raised upon the wicked things we've said." The 1960s was full of ditties about breaking up and falling apart. That Mad Menbucks history and pulls from the repertoire of the 1990's strongly emphasizes how a seemingly perfect midcentury family will come to reckon with the divides of modernity. From this point forward, the expanding gap between Don and Betty will drive the plot forward and force the protagonist to pose a series deeply existential questions. Their answers will shape the course of his family and the other characters at the agency."
