The members of the Piedmont East Bay Children's Choir are a vital part of the festival. They rehearse alongside visiting choirs, host performances and events, and represent the deep artistry of the Bay Area choral community. All Ecco singers are expected to participate fully in the festival; it will be a required component of the 2014-2015 Season. The expectations begin Sunday July 12 and continue through Sunday July 19, with multiple rehearsals and concerts during the week, along with festival-organized recreational activities.
Ecco families are strongly encouraged to homestay visiting singers; the relationships built in these exchanges have the potential to extend into future relationships, when PEBCC singers visit other cities and countries and stay with friends made here.
