In its 36th season, Lincoln Festival Chorus will perform Ralph Vaughan Williams’ “Dona Nobis Pacem” with soprano soloist Suzanne Nance and bass-baritone John David Adams, accompanied by the DaPonte String Quartet and pianist Sean Fleming and conducted by Anthony Antolini, Friday, Aug. 12; and Sunday, Aug. 14, at 7:30 p.m.

Friday’s performance is at the Opera House at Boothbay Harbor, 86 Townsend Ave.; and Sunday’s performance is at the Bowdoin College Chapel in Brunswick. The program also will include Randall Thompson’s “Alleluia”; songs by Samuel Barber and Ned Rorem performed by Nance; and movements from J.S. Bach’s “Art of the Fugue,” played by the DaPonte String Quartet.

Nance will return to Maine from her current position as program director and on-air host of All Classical Portland, a radio network with broadcast stations throughout Oregon. She formerly was music director and morning show host for Maine Public Radio, where she created, produced and hosted the Emmy-Award winning series “Maine Arts!” She has performed with Lincoln Festival Chorus before, in productions of “Carmina Burana” and the Mozart “Solemn Vespers” and “Regina Coeli.”

Adams studied voice at Hartt School of Music and the San Francisco Conservatory of Music; and he teaches voices at the Bay Chamber Music School. He recently performed the roles of Angel Raphael and Adam in Haydn’s “The Creation” at Bowdoin College; and the bass solos in the Mozart “Requiem” with Down East Singers and Mozart Mentors Orchestra.

Vaughan Williams’ “Dona Nobis Pacem” was composed between 1934 and 1936. The six-movement work sets the poetry of Walt Whitman and selected verses from the Old and New Testaments on the subject of the futility of war. The composer had served as an ambulance attendant in World War I and had become active in the World Federalism movement that advocated a United States of Europe and, eventually, a United States of the World. He originally scored “Dona Nobis Pacem” for large orchestra and chorus, but later downsized the work to strings, piano and chorus. It is this version that will be performed.

Adult tickets are $25; tickets for those younger than 18 and for members of the military on active duty are free, but must be picked up where adult tickets are sold. Tickets are available for both performances at Sherman’s Books in Boothbay Harbor and Damariscotta; A Silver Lining in Boothbay Harbor; and at the opera house. Tickets for the Bowdoin Chapel performance also are on sale at Gulf of Maine Books in Brunswick and the Silver Lining and Sherman’s Bookstores.

Any remaining tickets will be available at the door, which will open 7 p.m. For more information, call 633-5256.
