When Ann Williams started her modest dance company more than 30 years back, she probably had no aspirations to become an icon. From its humble beginnings in recreation centers, her company grew into the internationally acclaimed Dallas Black Dance Theatre and is soon to be one of the glittering jewels of the Dallas Center for the Performing Arts. The ensemble of 12 professionals performs a mixed repertory of modern, jazz, ethnic and spiritual works by choreographers who include Alvin Ailey, Talley Beatty, Donald Byrd and Alonzo King. These dancers enjoy a singular luxury in the world of dance: an 11-month contract. To keep up with demand, Ann Williams formed DBDT II, a semi-professional company of 12 aspiring artists from around the nation. When wishing good luck to dancers, never say "break a leg." But let's wish Ann Williams and her company another 30 years of great moves.
