Angella Foster's commissioned piece "Speechless" uses movement, text, live music and video projections to tell the stories of families who care for special needs children who cannot speak. Using her cousin Taylor's story and interviews with her aunt as a starting point, "Speechless" gives a voice to the struggle to love, communicate with, and care for a silent child in a noisy world. Thursday, Oct. 14, and Friday, Oct. 15, at 6 p.m. Kennedy Center Millennium Stage. Tickets are free. Call 202-467-4600 or visit kennedy-center.org.
