"Heimdalsgate Like a Promethean Curse" was the first single released by Polyvinyl Records from Of Montreal's 2007 album Hissing Fauna, Are You the Destroyer?. Like the rest of the album, the song was written, performed and recorded by Kevin Barnes.

"Heimdalsgate Like a Promethean Curse" was also released as a music video directed by The Brothers Chaps. The song opens up with a Roland Jupiter 8 bass into a lead made with a Sequential Circuits Prophet 5, along with A Linn Drum and an electric piano the quirky electronics give the song a 1985 feel.

In an early review of the song, posted shortly after the leak of the album in September 2006, Pitchfork Media's Andy Dubbin describes it as "one of the more breakneck, 'old Of Montreal'-styled songs on an otherwise discofunk-lite album, bringing proper attention to itself without overextending its theme."

In his review for Pitchfork, Dubbin suggests that "'Heimdalsgate' takes up the drugs-as-artistic-inspiration vs. drugs-as-personal-ruin dilemma and plays it out with equally conflicted musical gestures." According to Kevin Barnes, this interpretation is not valid. Asked "Are you a stoner?" by The Stranger's Christopher Frizzelle in direct reference to the song's "chemicals", Barnes says, "Yeah, that has nothing to do with drugs. That's the chemicals in your mind."

FRIZZELLE: Serotonin?

BARNES: Yeah. I went through this chemical depression, and that's when I was writing a lot of the songs for Hissing Fauna. They're all songs about that experience. And I was experiencing it in the moment that I was writing the songs, and sort of asking myself: What the hell is going on? Why are you all of a sudden totally paranoid and plagued by these anxieties? And why is everything so distorted and confusing and fucked up? My lifestyle hadn't changed that much. And then I realized, well, there's something going on inside of me that I don't have control over, and then you realize how vulnerable you are to these things, these elements that you can't understand, or unless you go on medication and get it under control. It's like you're being betrayed by your body.
