Three Rivers Chorus presents its fall concert “’It Is At Moments’” on Saturday, December 3, 8:00p.m., at Sudbury United Methodist Church, 251 Old Sudbury Road, Sudbury, MA.

The upcoming concert features songs from the jungles and the music conservatories Brazil; the jazzy compositions of Greg Jasperse; and works by Bach, Cage, Kodaly, Pevernage and Raminsh. The Gospel Choir of Sudbury United Methodist Church will be honored guest artists for the performance. A reception with refreshments and a silent auction will immediately follow the concert.
