A rare snowy day in Nashville, Tennessee set the stage for an even rarer event an intimate concert by rock icon Robert Plant at the War Memorial Auditorium. Performing with his new, Grammy-nominated group aptly titled the Band of Joy (which includes fellow luminaries Buddy Miller and Patty Griffin), Plant played both Led Zeppelin classics and new songs that continue to have an impact on the music scene today.

Filmed and Recorded Live at Ryman Auditorium, Nashville, Tennessee, on September 14, 2015, Nitty Gritty Dirt Band and Friends - Circlin' Back: Celebrating 50 Years captures a group of longtime road warriors who've yet to lose their grit, joined onstage by John Prine, Sam Bush, Vince Gill, Jerry Jeff Walker, Alison Krauss, Rodney Crowell, Byron House, and Jerry Douglas. Rock and Roll Hall of Famer (and early Dirt Band member) Jackson Browne joined in, along with longtime member Jimmy Ibbotson, while a sold-out crowd sings along in the background. From country classics to deep cuts, the tracklist finds bandmates Jeff Hanna (guitars/vocals), Jimmie Fadden (drums/harmonica/vocals), Bob Carpenter (keyboards/accordion/vocals) and John McEuen (banjo/fiddle/guitar/mandolin) swapping harmonies, trading solos, and shining new light on a catalog of vital, vibrant music.
