Creating unity through music is a driving vision of Latin Grammy–nominated Mexican vocalist Sonia De Los Santos and the American folk duo the Okee Dokee Brothers. With their act Somos Amigos: Songs on Common Ground, the trio will headline the Green Music Center’s free Family Day, sharing bilingual songs from the musical traditions of North America. The afternoon will also include a marimba performance, dance demos by Grupo Folklórico Quetzalén of Sonoma Valley, and percussion and hip-hop workshops. The event will be held on March 18, 12:30–5 p.m., at the Green Music Center in Santa Rosa. Find a schedule at gmc.sonoma.edu/somosamigos.
