Dave Matthews Band continued their run at the famed Greek Theatre in Berkeley, CA last night, and fans at the show were treated to a Grateful surprise: Bob Weir. The legendary guitarist came out in the middle of the show, joining Matthews and co for a performance of the Daniel Lanois song, “The Maker.” It was the band’s first time playing “The Maker” in 2016, with a gap of 121 shows prior to the bust out moment.

Though Dave Matthews and Bob Weir have shared the stage during a “Dave Matthews and Friends” performance in 2006, this marks the first-ever sit-in for Bob Weir with the DMB. Fortunately, thanks to YouTube user Daryl Primorac, there’s a full video of the 13-minute jam session with Bobby.
