Franz Joseph Haydn’s “Little Organ Mass” is a gem of the Classical choral tradition, with beautiful choral sounds and an ornate organ solo, to be played on a handmade continuo organ now on loan to the church from A. David Moore.

George Fredric Handel’s “O Praise the Lord” is a longer work for chamber choir, soloists, string trio and oboe. Those who love Handel’s “Messiah” may be pleasantly surprised to discover this charming piece, one of Handel’s famous “Chandos Anthems.”

The concert will be performed on Sunday, October 30 at 4:00 p.m. The First Religious Society, UU, is located at 26 Pleasant Street in Newburyport. Handicapped accessible, convenient adjacent parking. Suggested donation $15.
