Billie Eilish performed “What Was I Made For?” live for the first time during her headlining set at Lollapalooza.

Eilish co-wrote the song with her brother Finneas for the Barbie movie soundtrack.

Alongside the debut, Eilish’s set was powered by a solar farm at the festival. The environmentally-friendly performance was part of the Music Decarbonization Project co-founded with Eilish in partnership with the climate non-profit REVERB.
