Post Malone has been making the rounds in support of his new album Hollywood's Bleeding, which dropped last week. A few days back, he caught up with Kerwin Frost to chat about the project at length. Posty's tour photographer Adam DeGross was there to capture some B-roll and managed to snag some footage of him and Frost raging out to the end of Fleet Foxes' "The Shrine / An Argument,” which originally appeared on 2011's Helplessness Blues (yes, it still hits). The Foxes' Robin Pecknold posted the clip to his Instagram story, writing that it "made his day." Check it out below, and then read our take on Posty's new record Hollywood's Bleeding.
