THOMASTON — Advance registration is now open for Down East Singers, which will begin fall semester rehearsals on Sunday, Sept. 12, in a tent on the lawn at St. John’s Episcopal Church, at the corner of Main and Green streets. Rehearsals will continue Sundays from 1 to 3 p.m. through Oct. 10. The ensemble will prepare a free concert of all-American music to be performed on Sunday, Oct. 17, at 2 p.m. at the Camden Amphitheatre, co-sponsored by the Camden Public Library. In case of rain, the concert will be held on Sunday, Oct. 24, at 2 p.m. The performance, entitled “Comfort and Joy,” will include music from the Shakers and Quakers to gospel and jazz arrangements. The performance will be videotaped for later broadcast on Down East Singers’ YouTube channel.

Anthony Antolini of Cushing, the group’s artistic director, has conducted the ensemble since 1991. Jennifer McIvor of Wiscasset is the assistant conductor and accompanist. The guest soloist of the concert will be teenage fiddler Owen Kennedy, who will play fiddle tunes from around the United States.

Down East Singers is open to all community members, and new singers are welcome. Sight-reading skills are desired but not required, as long as an ability to match pitch is demonstrated. All singers are expected to work on their music at home between rehearsals. A free subscription to the My Choral Coach rehearsal platform is provided as soon as registration is received. This permits pitch and rhythm practice prior to rehearsals. The membership fee is $50, payable either through the website or by mail. High school students sing for free. Music for the semester will be provided through My Choral Coach as soon as registration is received, and in paper copies at the first rehearsal. Evidence of vaccination will be required for all members. To register or find out more, visit downeastsingers.org or call 207-619-0423.
