Post Malone has done covers before. If you search Youtube you'll come across a young Post covering Bob Dylan and a more recent cover was of Kanye's "Heartless." Now a new video has surfaced showing Post with his very own rock band covering Nirvana and Alice In Chains. Post Malone and Andrew Watt performed with their band Raw Dog as they performed "Lithium” and “Man in the Box” before smashing the shit out of a guitar, and Boomshots was their to get the footage. Throughout the performance the video cuts back and forth to an unofficial interview with Post where he talks his love for Rock, how he got started in music plus a bunch of other topics. Watch the clip above and let us know what you think of Post covering rock songs.
