More than 200 people from the United States, Canada, the Caribbean and Africa will sing scriptural music in a festival May 15-18 at the Baha'i House of Worship in Wilmette.

The singers also will present a concert at 12:30 p.m. May 18 inside the 1,200-seat House of Worship, at Linden Avenue and Sheridan Road. The choir will then sing outside, weather permitting, on the House of Worship stairs at about 1:30 p.m. The concerts, performed without instrumental accompaniment, are free and open to the public.
