Before "O Brother..." Came Circle

The Nitty Gritty Dirt Band will further celebrate the thirtieth anniversary of their classic recording, Will the Circle Be Unbroken, with the release of Will the Circle Be Unbroken, Vol. III on October 1st. The group has again brought an all-star group of guests onboard for the project, recorded in May and June in co-producer Randy Scruggs' Nashville studio. The visitors this time around include bluegrass greats old (Jimmy Martin, Earl Scruggs), less old (the Del McCoury Band, Sam Bush) and relatively new (Alison Krauss). A spectrum of country stars are also participating, including Johnny Cash, Willie Nelson, Emmylou Harris, and Dwight Yoakam. Tom Petty "makes a cameo," according to the Dirt Band's Jeff Hanna, to represent rock & roll, while Taj Mahal and Doc Watson bring the blues and folk, respectively.
