JOHNSON CITY, Tenn. (AP) — The Great Smoky Mountains Association is releasing a third album of traditional American music in conjunction with the National Park Service’s 100th anniversary.

East Tennessee State University said in a news release that Appalachian studies faculty member Ted Olson is the producer for “On Top of Old Smoky,” while bluegrass, old-time and country music studies faculty member Roy Andrade is the associate producer. Others with the university were also involved, and much of the recording took place in the ETSU recording lab.

Free concerts to launch the album are set for Aug. 20 at the Great Smoky Mountains National Park Oconaluftee Visitor Center and Sept. 10 at the park’s Sugarland Visitor Center.

The association’s first album was nominated for a Grammy, while the second was nominated for an International Bluegrass Music Association award.
