Chicago-based performance art group Environmental Encroachment (EE) uses circus theatrics, live music and costumes to create unique entertainment environments, parades, processions, concerts, D.I.Y. activist marching band encroachments, and art happenings.
EE combines a costumed marching band with multi-media stage performance antics, including dancers, invented instruments, hooping, juggling, puppetry, and skits.
