Last February, U.K. pop chanteuse Charli XCX told Billboard all about her musical obsessions -- and she name-checked the Spice Girls, but didn't mention another best-selling 90s vocal group, the Backstreet Boys. Well, she made up for that omission by covering BSB's classic "I Want It That Away" during a performance at Borderline Music in Chicago on Tuesday (May 21).

The stripped-down take on the boy band hit trades the original's sunny disposition for a heaping helping of goth glam, as Charli's voice quivers when the chorus kicks in. The soulful performance was the singer's first live take on the song, and she might bust it out again later on this tour, which continues on Wednesday night in Detroit.

"True Romance," Charli XCX's debut album, has sold 4,000 copies since its release last month, according to Nielsen SoundScan. The singer is featured on Icona Pop's "I Love It," which holds steady at No. 9 on this week's Hot 100 chart.
