Ice Cube and Perry Farrell also appear in the clip for the YouTube Original film, which will stream for free beginning April 10 - the date the postponed 2020 festival was originally due to begin.
"Everybody knows what Coachella is," Eilish says in the opening moments of the video. "Even if you don't care about music, you know."
Later, Ice Cube highlights the massive publicity that the event attracts, with Farrell reflecting: "You're gonna be judged, man, when you hit Coachella's stage. And it's gonna be talked about for the rest of the year, so you better get your s**t right."
Toward the end of the teaser, Moby reflects on performing at the first Coachella in 1999, gushing over the "remarkable" idea of staging a festival in the middle of the desert.
The 2020 Coachella was postponed to October due to the coronavirus pandemic. Promoters of the festivals remain hopeful Travis Scott (II), Frank Ocean and Rage Against the Machine will still be on board to lead the line-up for the rescheduled event.
