Don Henley announced his first new solo album in 15 years on Friday. It’s a country collection called Cass County, which will feature legendary collaborators like Merle Haggard, Mick Jagger, Alison Krauss, Vince Gill and Dolly Parton.

The album gets its name from Henley’s birth town in Northeastern Texas, and while the genre seems far from The Eagles’ repertoire, Henley assures fans he’s always had country in his blood. “I was born and raised in Texas,” he said in a statement. “I’m a Southerner and a Texan. This is a natural progression for me. It’s who I am and where I come from.”

The Eagles drummer, singer-songwriter and producer also shared two new songs from the album on NPR’s “All Things Considered”: “That Old Flame” featuring Martina McBride and “Take A Picture Of This.” Both were co-written by Stan Lynch. Cass County is due out Sept. 25 via Capitol Records.
