Justin Vernon performs with Dead and Company in Wisconsin: Watch

In 2016, Justin Vernon contributed a cover of Grateful Dead’s “Black Muddy River” to the Red Hot Organization charity compilation, Day of the Dead. That summer at the Eaux Claires Music Festival, Vernon staged a Grateful Dead-themed jam session featuring Bruce Hornsby, Jenny Lewis, Phosphorescent, and more. Needless to say, the Bon Iver mastermind is a pretty big fan of the Dead, and last night he got a chance to play with the band’s surviving members in person when he joined Dead and Company on stage at Wisconsin’s Alpine Valley.

Per Live Music Blog, Vernon joined the Dead’s Bob Weir, Mickey Hart, and Bill Kreutzmann, along with John Mayer, for performances of “Black Muddy River”, “Friend of the Devil”, and “Bird Song”. “Nbd sitting in with the dead tonight at alpine,” Vernon tweeted prior to the show.
