In 1981 the dance journalist Celia Ipiotis created this talk show, which aired on public television until 2006. Lately she's been screening episodes from the archives as part of Gibney Dance Center's "Sorry I Missed Your Show" series. The next installment, "The Language of Dance," features a 1990 episode in which Christine Dakin, Neil Greenberg and Vicky Shick - who danced with Martha Graham, Merce Cunningham and Trisha Brown, respectively - discuss the vocabulary, verbal and physical, used by those choreographers. The video guests will be there in person, too, for a more current conversation on similar topics.
