“Purge the Poison” is the second single from Marina’s fifth studio album, Ancient Dreams in a Modern Land.

On May 14, 2020, Diamandis released a snippet of the song on her Instagram and Twitter. On March 14, 2021, Marina posted a picture of red nails and a mannequin wearing a wig with a camera emoji on her Instagram, hinting at a music video. This was followed by an image talking about Jeffrey Epstein’s Mansion with the following quote: “It’s a new world order”.

On April 12, 2021, the music video accidentally leaked on Marina’s official music channel and was shortly removed after the upload. Hours later Marina posted a tweet showing the track’s release date.
