Watch Post Malone Cover Nirvana's "Lithium" at Coachella

ThoughPost Malone wasn't listed on the official lineup for Coachella 2016, the singer and rapper had himself a big weekend that included a guest appearance during Jack Ü's set on Friday night. Well, Post wasn't done there, as he was spotted later in the weekend jamming out on a guitar and covering Nirvana's classic song, "Lithium." While it's no secret that Post is a beast on the guitar, it's always fascinating to see him shred and step out of the rap lane as often as he does.

For Post, he currently has a mixtape on the way, and then his debut album is slated to drop at some point in 2016. He's also on the road with Justin Bieber at the moment, which has been a crazy experience in its own right, with Post slaying his opening set on the tour, though him and the Biebz maybe got into a little bit of a scuffle. Regardless, Post is out here winning on all fronts.
