Alvin Ailey American Dance Theaters signature work, Revelations, is one of the most well-known pieces in contemporary dance. Even the 1976 photo that captured the ballets highlight (dancer Judith Jamison with her right leg swinging effortlessly high above her head, while she stands in a flowing white dress) has become an icon. Its Jamison, who went on to become the companys artistic director after Aileys death, who brings the company to Houston now as part of its 50th anniversary. And yes, Revelationsis on the program. So is Suite Otis, a collection of six dances set to the music of Otis Redding including Ive Been Loving You Too Long and Try a Little Tenderness, and Go in Grace, accompanied with an onstage performance by a cappella group Sweet Honey in the Rock. (A little Alvin Ailey trivia: 1. Ailey was born in Texas. 2. Theres an Alvin Ailey Barbie doll, and shes costumed in a Revelations-like dress. 3. This is Jamisons last planned visit to Houston as AD; she retires in 2011.) 8 p.m. Friday and Saturday, 2 p.m. Sunday. Society for the Performing Arts, Jones Hall 615 Louisiana.
