Ecstasy is one of Lou Reed's later albums (his 18th), and it's all about the malaise of modern life, especially when it comes to a love gone stale ("It's all downhill after the first kiss). In "Modern Dance," he sings about all the places he could go to escape these doldrums, figuring that a change in location might solve his problems. But, he is gripped with indecision, as his options are overwhelming: Amsterdam? Tangiers? The Yucatan, where they have clear gender lines? The barrage of choices seem to be a coping mechanism that will keep him from taking any real action.
Reed made a video for this song where he's dressed in a chicken suit. Female dancers pluck his feathers off until there are none left, but then put him in a pot to reattach them. The video was directed by Stefan Sagmeister, who primarily works in design.
The 2006 Peter Bjorn and John song "Amsterdam" was inspired by this track.
Kacey Musgraves originally offered "Follow Your Arrow" to her friend Katy Perry. However, Perry thought Musgraves should record the song herself as it seemed, "like something that you would totally say."
