PORT TOWNSEND — Performing for the first time in the Candlelight Concert Series, Professionally Relaxed Musicians will play at 7 p.m. Thursday, showcasing “Folk Music Yesterday and Today.”

The concert will be at Trinity United Methodist Church, 609 Taylor St.

Doors will open at 6 p.m. Admission is by a suggested $10 donation and children will be admitted free.

The program will feature selected original music composed by Lis Nagy and Larry Costello as well as a selection of other songs by prominent folk music composers.

Nagy says of their group, “PRM celebrates the wonderful folk music tradition as we sing and play on Washington’s Olympic Peninsula. We perform a mix of familiar, original and traditional folk music.”

PRM also will share musical favorites by iconic performers including Kenny Loggins’ “Danny’s Song,” John Denver’s “Country Roads” and “Wagon Wheel” by Old Crow Medicine Show.

Other composers featured in the evening’s performance will include Woody Guthrie, Stevie Nicks, John Mellencamp, Tom Petty, Crosby, Stills, Nash and Young, and the Beatles.

Costello was a cornerstone of the ever-popular Port Townsend folk bands Shady Grove and Dream City Ramblers, plus many other groups.

With the Dream City Ramblers in the 1990s, he played at the first Port Townsend Farmers Market, the opening of the Larry Scott Trail and the dedication of the Chetzemoka Park gazebo. He sang with Shady Grove for six years, playing the songs of the Kingston Trio, the Brothers Four and other iconic folk artists.

Nagy is a singer-songwriter who released her first album, “House of Music,” in 2015. For someone who has always loved to write, composing lyrics has been a natural segue into the musical realm.

She has an active YouTube channel that features her many thoughtful and evocative compositions.

PRM will feature many of Nagy’s songs during the performance.

Said Nagy: “Sharing music with the rest of the world is a dream come true.”

Supporting Nagy and Costello on bass will be Hank Snelgrove, a local remedial double bass player. He has accompanied groups such as The Standbys, Shady Grove, The Mojitos, The Road agents, The Marrowstone Mountain Boys and other bands.

Refreshments will be served following the performance.
