Convoco, a project-based, professional choral collective based in Philadelphia, will perform “Not One Sparrow is Forgotten,” a program featuring works of Barber, Briggs, DiOrio, Pärt, Purcell, Taverner, and other composers on Sunday, June 29 at 4 p.m. at All Saints Church, 16 All Saints Road. Admission is free, and donations are accepted.

The ensemble’s core of 13 musicians work in the New York, Philadelphia, and Washington D.C. metropolitan areas. They share a passion for small ensemble singing, education, and community engagement.

This season, Convoco has focused on works by living composers. This has included several recording projects (stay tuned), concerts, and a continued residency at Drew University, where the choir works with the University’s composition students.

Recent seasons have included a tour of the Mid-Atlantic region, a residency at the Avaloch Farm Music Institute, and several concerts in the Philadelphia area. Future projects include new works by living composers as well as motets and madrigals from the pre-Baroque.
