Charli XCX is already in the spotlight after her hyper-pop-electronic album BRAT already debuted as the “most critically acclaimed album of the year,” beating out Beyoncé’s latest album Cowboy Carter and Taylor Swift’s The Tortured Poets Department.
At number one on Metacritic, Charli’s new album BRAT surpassed Queen B’s hit country-pop album Cowboy Carter, which was released on March 29 and is the singer’s eighth studio album.
According to review aggregator Metacritic, it received “universal acclaim” based on a score of 92 out of 100 from 11 critics.
BRAT is the singer’s sixth studio album and the record reportedly evokes and channels London’s illegal rave scene, where Charli began performing when she was 14 or 15 years old.
According to Charli XCX, BRAT is her “most aggressive and confrontational” album, but also her most vulnerable.
