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.

Former Pilobolus member Peter Pucci is creating the dance and the other choreographers -- Laura Dean, Charles Moulton and Margo Sappington -- have all made ballets for the Joffrey in the past.
