Warren Haynes is hot on the touring trail as he and his Ashes & Dust Band rolled into Raleigh, NC over the weekend for the inaugural American Roots Music & Arts Festival. With plenty of talented musicians around (Tedeschi Trucks Band, Greensky Bluegrass, Railroad Earth, Modest Mouse, The Roots) there was bound to be a sit-in, and who better than Haynes to oblige?

After headlining the festival for two nights, country superstar Eric Church summoned Haynes to the stage for a timeless rendition of The Band’s “The Weight” on Sunday night and delivered an unforgettable moment. Memphis product Joanna Cotten brought her sterling vocals to the party, too. Take a look at some fan-shot video of the performance below:
