While the musician has played several performances at live one-off events, this was her first concert of the year proper, following restrictions brought by the ongoing pandemic.

Speaking to the audience in Las Vegas where she was performing at the iHeartRadio Music Festival, Rodrigo said: “This is a really special day for me because this is sort of like my first show.”

“I’m just so grateful that you guys are here with me experiencing this. Thank you so much.”

She continued: “Speaking of firsts, this is the first song I put out,” she said, sitting at the piano to begin “Drivers License.”

After the performance, which the audience sand along to in unison, Rodrigo replied: “You guys are just like the best crowd ever. This is amazing.”

Rodrigo recently performed her track ‘Good 4 u’ at the 2021 MTV Video Music Awards ceremony.

The live rendition sees Rodrigo backed by a full band, as well as a troupe of choreographed dancers.

‘Good 4 u’ is lifted from her debut album, ‘Sour’, which arrived back in May through Polydor.

NME gave the album four stars upon its release, writing “pop’s brightest new thing proves she’s not just a flash-in-the-pan, but a multidimensional artist who’s in it for the long haul”.

“With typical Gen-Z versatility, she hops from genre to genre without losing sight of herself and doses her songs with bitingly specific details that go full-circle from being precisely personal to universally relatable.”
