Penn’s Peak announces Nitty Gritty Dirt Band will appear at 8 p.m. Sunday, Oct. 6.

The Nitty Gritty Dirt Band remains one of the most accomplished bands in American roots music.

Following an extended 50th anniversary tour, the ensemble grew to a six-piece in 2018 for the first time since their early jug band days. The group now includes Jeff Hanna on acoustic guitar and electric guitar; Jimmie Fadden on drums and harmonica; Bob Carpenter on keyboards; Jim Photoglo on bass and acoustic guitar; Ross Holmes on fiddle and mandolin; and Jaime Hanna on electric and acoustic guitar. All six members also sing, and the band carries on a country music tradition of blood harmony.

“It’s like when you throw a couple of puppies into a pen with a bunch of old dogs. All of a sudden, the old dogs start playing, you know? That’s kind of what’s happened with us,” Jeff Hanna said.

Tickets go on sale at 10 a.m. Friday.
