THOMASTON and ROCKPORT — Down East Singers, a choral group that enjoys changing its musical style each December, will collaborate with the folk trio T-Acadie and pianist Jennifer McIvor in a concert entitled "Noël Français" on Friday, Dec. 9, at 7:30 p.m., at Watts Hall, 174 Main Street, Thomaston; and Sunday, Dec. 11, at 2 p.m., at the Rockport Opera House. Anthony Antolini of Cushing will conduct the concerts.

The performances will feature French-Canadian and European French holiday choral music and Acadian folk music played by T-Acadie. The groups will combine to perform lively dance tunes such as "Si mon moine voulait danser," arranged by Québec composer Donald Patriquin. Old favorites include Adolph Adam's "Cantique de Noël," with tenor soloist Hayden Sears, and new repertoire with soprano Robyn Tarantino as soloist in "Make me a channel of thy peace," which combines the Bach-Gounod "Ave Maria" with a setting of the Prayer of St. Francis.

Admission is $20. Those 18 and younger are admitted free, but must have a ticket.

Tickets for the Thomaston performance are on sale at Flaura Flowers & Wine, 185 Main St., Thomaston.

Tickets for the Rockport performance are available at The Grasshopper Shop, 400 Main St., Rockland

And for either performance, tickets can be ordered through the group's website, downeastsingers.org.
