Keep scrolling below for all of the highlights from the 2021 iHeartRadio Music Festival.

Cheap Trick

Cheap Trick treated everyone to a trip down memory lane with performances of their biggest hits over the years, including "I Want You to Want Me," "Dream Police" and "Surrender."

Walker Hayes had everyone singing about Applebees on a date night and Oreo shakes with his hit song "Fancy Like."

FINNEAS

FINNEAS is dropping his debut album, Optimist, next month, and previewed the project with his iHeartRadio Music Festival set — and rocked the house with his closing song "The 90s."

Darius Rucker

Darius not only performed some of his country hits ... he brought back Hootie & the Blowfish with "Only Wanna Be With You." And, what's more iconic than closing with fan favorite "Wagon Wheel?"

Weezer

Weezer rocked the house with all the fan favorites like "Beverly Hills," "Hash Pipe," "Holiday In The Sun," their Toto cover of "Africa," "Say It Ain't So" and "Buddy Holly" ... all with Rivers Cuomo in an iconic mullet and mustache.

J. Cole

Nelly with Special Guests Florida Georgia Line

Nelly closed out Night One with an amazing performance of fan favorites (the nostalgia was REAL) — including a few of his collaborations with Florida Georgia Line.

NIGHT 2

Billie Eilish

The 19-year-old artist opened up the second and final night of the festival alongside her brother and collaborator Finneas on backup vocals. Billie's electric setlist consisted of fan-favorite songs from her 2019 album When We All Fall Asleep, Where Do We Go? and her sophomore outing Happier Than Ever.

Sam Hunt

The country crooner turned the iHeartRadio Music Festival stage into his very own house party.

Coldplay

Just when you thought the 2021 iHeartRadio Music Festival couldn't get any better, Coldplay hit the T-Mobile Arena stage to perform some new tracks like their latest single "Higher Power" and some fan-favorites, including "Viva La Vida and "Fix You."

Lil Baby

Baby dipped in his 2017 bag and gave the audience a dose of nostalgia, performing "My Dawg". But the fun didn't stop there. It wouldn't be a Lil Baby show if fans didn't get to hear his 2020 TikTok anthem, "Woah" -- which he performed alongside a few young TikTok dancers.

Khalid

The 23-year-old soul singer vibed out along with fans to his hit records "Talk", "Young, Dumb & Broke" and "OTW". He also surprised the crowd by bringing out Tate McRae to perform their summer anthem "working".

THE Kid LAROI

After hitting the Daytime Stage earlier in the day, the 18-year-old Aussie returned to the iHeartRadio Music Festival stage to deliver several of his fan-favorite hits.

Journey

The band got the crowd off their feet with striking vocals from Arnel Pineda and rock star performances from Neil Schon, Jonathan Cain, Deen Castronovo, and Marco Mendoza. They saved 'Don't Stop Believin' for the big finale, of course, and the crowd was showered with confetti as the final notes played.
