Rhiannon Giddens and Abigail Washburn dance together

It isn't every day you get to see artists like Punch Brothers, Lonesome Trio, Trampled By Turtles, Shaky Graves, and more come together on stage. But they did just that toward the end of The Bluegrass Situation Superjam at Bonnaroo 2015. Rhiannon Giddens and Abigail Washburn joined in on the music in between their dancing together.
