Just two days before Coachella was set to announce Kanye West as one of the festival's headliners, the the unpredictable hip-hop artist sprung a last-minute demand on festival executives—a dome, Billboard reports. Instead of performing on the main Coachella stage, West asked the festival to construct a giant, custom-built dome in the middle of the concert grounds. When senior executives explained to West, who was on vacation with his family at the time, that the dome would be impossible to build in four months and would require them to rearrange the entire festival site, West became irritated, reportedly declaring that he was an artist with a creative vision and hung up. Before the day was over, Coachella had replaced Kanye with Ariana Grande as the main headliner.
