Billy Strings was doing what he does best and putting on a wicked show in Los Angeles at the Observatory, and in a pleasant turn of events, called his buddy Post Malone onto the stage to cover an iconic Johnny Cash song!

"I saw this guy lurking around backstage," Strings can be heard saying. "So [I] figured [I] should drag him up and sing."
