Coachella very nearly landed Kanye West to headline this year’s festival, and porta-potties are to blame for his exit. Or rather, the porta-potties that stood in the way of promoters fulfilling West’s demand for a giant, domed performance space.

Billboard assembled the wild details of West’s ouster from the desert festival, which paved the way for Ariana Grande’s headline gig. According to insiders, West insisted that collaborator and set designer John McGuire be allowed to construct a dome “tricked out with high-tech production and immersive video” for his performance, but Coachella parent Goldenvoice shot back that not only was such a feat impossible in four months, they’d also need to re-arrange the festival site and remove a section of portable bathrooms to accomplish it.

“West became irritated, declaring that he was an artist with a creative vision who shouldn’t be spending his time talking about porta-potties,” Billboard reported. He subsequently hung up the call, and Goldenvoice moved on from recruiting him. The artist’s demand for a domed stage also previously derailed his headlining slot at Governors Ball in New York.

West would have played in the dome’s center as an in-the-round performance; likely an effort to surpass the infamous flying stage he utilized for a 2016 tour. He reportedly complained the main Coachella stage wasn’t big enough for his performance, despite past headliners fitting “hundreds of dancers and musicians” in their act.

Nonetheless, this year’s Coachella will take place the weekends of April 12 through April 14 and April 19 through the 21.
