LOS ANGELES -- Prince, the flamboyant rocker, composer and filmmaker, will enter the concert dance field in a collaboration with four American choreographers, providing music for a full-evening work for the Joffrey Ballet's 1992-'93 season, company artistic director Gerald Arpino announced yesterday.
Titled "Billboards," the four-part ballet will premiere in Iowa City next January, but a pas de deux from it is scheduled to be danced in Los Angeles in May and June of this year.
