This is a track from Foster the People's second album, Supermodel. Mark Foster told The Sun: "That song is so much fun to play live. It's my favorite song lyrically, and it's the most poignant representation of all the themes of the album."
"I waited until the very end to write all the lyrics, which I've never done before," he continued. "It was really hard and if things that came out of it will these subconscious cyclical themes."
"I had gasoline pumping through my veins, Foster added. "It's about capturing that moment in time."
The song samples the beat of A$AP Rocky's Long.Live.A$AP track, "LVL."
It was never a big hit, but "She's A Rainbow" became one of the most popular Rolling Stones songs in the digital age when it started showing up in commercials (iMac, Photoshop), and TV shows (American Horror Story: Coven, Ted Lasso).
