Watch Billie Eilish cover Gorillaz’s “Feel Good Inc.” with Damon Albarn at Coachella

Billie Eilish‘s Coachella set featured a surprise appearance by Blur and Gorillaz frontman Damon Albarn.

The “bad guy” artist invited Albarn on stage for a joint performance of her song “Getting Older,” as well as rendition of the Gorillaz classic “Feel Good Inc.”

For the “Feel Good Inc.” performance, Eilish and Albarn were also joined by Posdnuos of hip hop trio De La Soul, which provided the iconic rap verses on the original song.

Albarn is an Eilish fan, and has covered “Getting Older” himself. In the infamous Los Angeles Times interview where he claimed Taylor Swift “doesn’t write her own songs,” Albarn called Eilish a “really interesting songwriter.”
