The songstress' iHeartRadio Festival set marked her first arena gig since her Where We Do Go? World Tour was postponed in March 2020 as a result of the coronavirus pandemic.
During her five-song set, Eilish performed "My Future" and the title track from her sophomore album, Happier Than Ever, which debuted at No. 1 on the Billboard 200 in early August. She also played “Bury a Friend,” “Bad Guy” and “Oxytocin," from her 2019 debut album.
Other performers on the 2021 iHeartRadio Festival bill included Coldplay, Dua Lipa, Olivia Rodrigo, Florida Georgia Line, Lil Baby, Maroon 5 and others.
While in Sin City, Eilish will also headline the closing day of the Life Is Beautiful in downtown on Sunday. In the coming weeks, she's scheduled to perform at numerous other music festivals, including Delaware’s Firefly Festival, New York’s Governors Ball and Texas' Austin City Limits Festival.
Early next year, the singer will embark on a 32-date North American arena tour before heading overseas for shows in Europe and the United Kingdom. Eilish recently previewed songs from her latest album in her new concert film, Happier Than Ever: A Love Letter to Los Angeles, which premiered on Disney+ in early September.
