Following her 2023 signing with RCA Records, McAlpine released her third studio album, Older, on April 5, 2024, which was supported by the lead single of the same name.

Born and raised in the suburbs of Philadelphia in the state of Pennsylvania, McAlpine began gaining recognition by posting original songs and covers online on the platforms SoundCloud and YouTube.

She studied abroad in Spain in the fall of 2019, where she wrote her debut studio album, Give Me a Minute, which was released in August 2020.

[18][19] The Dallas Observer named it one of the best albums of 2020,[20] and BBC Media Centre has called her an "up-and-coming vocalist".

She cancelled the UK and Europe dates of this tour citing mental health reasons and feeling burnt out.

[40] To promote the project, she will embark on the Older Tour through North America and Europe, starting on April 21.

[17][18] Her collaborators include Jacob Collier, Dodie, Tom Rosenthal, Ben Kessler, Noah Kahan, John Mayer, Niall Horan, Finneas, and Thomas Headon.
