The War & Treaty, Sierra Ferrell and Junior Brown are among the final round of artists announced at a press conference today for the 21st Annual Bristol Rhythm & Roots Reunion music festival, which takes place Sept. 9-11 in Historic Downtown Bristol, Virginia-Tennessee. Molly Tuttle & Golden Highway, Dustbowl Revival, and GRAMMY Award-winning country music stalwart Jim Lauderdale are also on the bill.

Sometimes, the most unexpected music moments are the ones you'll remember best. This will definitely be the case of my last Friday. Starting off the day, I had no idea I would be at the Fox Theatre in Boulder that night...witnessing the mesmerizing force of nature that is Sierra Ferrell and her band. Full disclosure, I didn't know who Sierra Ferrell was. However, as moments like these tend to happen, that day would have been my deceased father's 76th birthday.

With her spellbinding voice and time-bending sensibilities, Sierra Ferrell makes music that's as fantastically vagabond as the artist herself. Growing up in small-town West Virginia, the singer/songwriter/multi-instrumentalist left home in her early 20s to journey across the country with a troupe of nomadic musicians, playing everywhere from truck stops to alleyways to freight-train boxcars speeding down the railroad tracks.
