The Australian band Crowded House originally recorded “Don’t Dream It’s Over,” and it became one of those slow-rock, dreamy hits that characterized the late ’80s and early ’90s so well. Their version came out in 1986, which was before Miley Cyrus, Ariana Grande, or I was born, but maybe like me, the two pop stars heard Sixpence None The Richer’s excellent 2003 version. (I mean, it was on a Smallville compilation soundtrack, how could anyone miss that?) Cyrus recently launched a charity organization called the Happy Hippie Foundation that seeks to help marginalized LGBT homeless youth and has been posting backyard jam sessions to help get out the word — including an awesome collaboration with Laura Jane Grace on “True Trans Soul Rebel.” I was really into the one Cyrus did featuring Melanie Safka, “Look What They’ve Done To My Song Ma,” but her new duet with Ariana Grande tops that folk classic. The two sat on a neon blow-up couch and sang “Don’t Dream It’s Over” as a duet — even if you’ve decided you’re somehow above the pop music these two talented women make, this cover is worth hearing. It’s moody, romantic, and hopeful. Plus they sound fabulous together; Cyrus scratchy and low, and Grande with her velvet soprano. Watch it below.
