Bob Weir joined the Lampedusa ensemble during their set at Hardly Strictly Bluegrass Festival in California, which features Steve Earle, Patty Griffin, Emmylou Harris, Buddy Miller and Lucinda Williams performing in a collaborative environment.

Weir emerged during Earle’s section of the show for a collaboration with Buddy Miller and Earle on “I Know You Rider,” with the guitarists leading the charge in an acoustic reading of the song. Watch the tune below.

Later on in the night, Weir ventured over to Lukas Nelson and Promise of the Real’s late night show following the conclusion of music at Hardly Strictly for a sprawling “Althea” with Nelson and the band. Watch that here.
