Dave Matthews hosted a benefit to support the Standing Rock Sioux Tribe in its opposition to the Dakota Access Pipeline. Matthews welcomed a host of artists including Neko Case and Graham Nash, both of whom joined Matthews and Tim Reynolds during their headlining set.

Case first appeared a couple of songs into the duo’s acoustic set for Daniel Lanois’ “The Maker” while Nash and his guitarist Shane Fontayne came out for CSN’s “Teach Your Children,” a debut for Matthews and Reynolds.

In the encore of the 13-song set, the duo delivered a song titled “Song for Billijo,” which Matthews described as an ode to a kindergarten teacher he met at Standing Rock Elementary School, played prior to the “Two Step” finale. Read the full lyrics here.
