Alessia Cara, who made herself into the music worldâs over-it young sister with her bored-at-the-party anthem âHere,â stopped by BBC Radio 1âs Live Lounge to dress down a few a tracks by other artists. Cara pulled off an acoustic âHotline Bling,â heavy on the guitar with a bit more swaggering syncopation that the 6 God usually employs. And in what hopefully prefigures the ultimate cool-girl collaboration, Cara also took a swing at Lorde and Disclosureâs âMagnets.â Seriously, can you imagine what an Alessia Cara and Lorde track would be like? A minor chord smudged with black lipstick? A leather jacket and the melody that isnât a melody when the music stops playing at a house party? Whatever it sounds like when your DNA simply unwinds? The world needs to know.
