 In front of a crowd at the Rotterdam Music Hall, Prince and his band perform 13 numbers, 11 of which are from his double album, "Sign  o  the Times," and all but "Now s the Time" are his compositions. This is high energy stuff, with neon signs flashing above the stage, suggesting the honky-tonk district of a big city. Between a few of the numbers, there are vignettes of street life. Three women - Shiela E, Boni Boyer, and Cat - provide rhythmic, vocal, and physical pyrotechnics. Sheena Easton appears in a film within a film, her rock video "U Got the Look." In constant motion, never far from center stage, is Prince, Minnesota s charismatic pixy.
