This fall, the Nitty Gritty Dirt Band will release "Will the Circle Be Unbroken, Vol. 3." The Capitol Nashville album is the latest installment in a guest-laden exploration of folk and country roots music the band first began in 1972 when it teamed up with such legends as Mother Maybelle Carter, Merle Travis, Doc Watson, Jimmy Martin, and Roy Acuff to release the groundbreaking "Will the Circle Be Unbroken."

This time around, NGDB -- John McEuen, Jeff Hanna, Jimmie Fadden, Jimmy Ibbotson, and Bob Carpenter -- co-produced the set with by Randy Scruggs and collaborated with a host of talent, young and old. Among those who mine traditional songs with the Dirt Band are Iris Dement, Jimmy Martin, Johnny Cash and June Carter Cash, Taj Mahal, Doc Watson, Emmylou Harris, Willie Nelson, Earl Scruggs, Alison Krauss, the Del McCoury Band, Matraca Berg, Dwight Yoakam, Tom Petty, Sam Bush, Jerry Douglas, Tony Rice, and Vince Gill.

"Vol. 3" comes just a few months after Capitol's 30th anniversary reissue of "Will the Circle Be Unbroken." The second volume was released by MCA in 1989 and featured the likes of Cash, John Denver, Bruce Hornsby, Ricky Skaggs, Chris Hillman, Roger McGuinn, Rosanne Cash, Steve Wariner, Roy Acuff, Chet Atkins, and returning friends Acuff, Martin, and Scruggs.

Last year marked the return of co-founder McEuen to the NGDB fold after several years of solo pursuits, as well as the hard-touring band's return to the road after a year-long break. The group will kick off a summer North American tour Sunday (June 30) in Colorado Springs, Colo. That run will come to a close Sept. 1 at the Watershed Festival in Walkerton, Ontario. The Dirt Band is also slated to perform Sept. 20-21 at Switzerland's Gstaad Festival, which will also feature performances by country artists Clay Walker and Chely Wright.
