Nashville, TN -- For five decades, the Nitty Gritty Dirt Band has remained one of the most iconic names in American roots music. With one foot planted in the traditions of country-folk and the other pointing toward something new and unexpected, the group continues to tour and release music, influencing multiple generations of audiences and artists along the way. Nearly a dozen of those artists join the group on this year's Nitty Gritty Dirt Band & Friends - Fifty Years, Circlin' Back! PBS special, which was nominated for a Midsouth Regional EMMY® for Special Event Coverage on Friday. Produced for PBS by Todd Squared, Todd Jarrell, Todd Mayo, Steve Schweidel, and directed by James Yockey, Circlin' Back ran nationwide in conjunction with a PBS pledge drive in March 2016. Circlin' Back is also available as a cd/dvd combo with bonus songs and interviews, released Sept. 30 via Warner Music Nashville.
