Although at 61, and after 40 years of performing, Bill T. Jones could respectfully retire, the iconic choreographer believes that an artist is “committed to participating in the world of ideas…and as an artist, are you willing to help build this world?” Jones has done much to help build the world of dance, and this month the Bill T. Jones/Arnie Zane Dance Company celebrates its 30th anniversary season, with Jones as executive artistic director of New York Live Arts, the Chelsea performance venue created through a merger between Dance Theatre Workshop and the company Jones founded with his partner of 17 years, Arnie Zane, who died of AIDS in 1988.
