Olivia Rodrigo Plays Her ‘First Show’ at 2021 iHeartRadio Music Festival: Watch

“This is a really special day for me because this is sort of like my first show,” she told the crowd from the fest’s daytime stage on Saturday (Sept. 18). “I’m just so grateful that you guys are here with me experiencing this. Thank you so much.”

“Speaking of firsts, this is the first song I put out,” she said, sitting at the piano to begin “Drivers License.” As she played her hit, she encouraged the audience — where some fans were spotted in Olivia Rodrigo and Sour tees — to join in, though she didn’t have to. They were already singing along before she could say “let me hear ya.”

Seemingly overcome with emotion over the experience, Rodrigo gushed, “”You guys are just like the best crowd ever. This is amazing.”

Rodrigo’s set continued with “Traitor” followed by “Good 4 U” as the closing number, and then she shouted out a “thank you” to Vegas as she blew kisses and ran off the stage.
