TWEEN LARYNXES, start your engines. The fourth annual "Scream Tour" hits Washington on Friday, offering frenzied fans that special, once-a-summer opportunity to shriek along with the latest crop of post-Jackson 5 heartthrobs at ear-splitting volumes. Bow Wow, Omarion and Pretty Ricky are all on this year's docket, having recently sugarcoated the airwaves with their respective singles "Like You," "Touch" and "Grind With Me." Odd man out Bobby Valentino is a welcome addition to the bill, and hot-to-trot after crooning the irresistible hook of Ludacris's summer banger "Pimpin' All Over the World." Sure, the 25-year-old Valentino might be the only "Scream" artist old enough to order a martini, join the Marines and rent a car in the contiguous 48 states -- but he's also the only one to deliver his syrupy R&B with such a cool-headed swagger.

"SOULS OF NAPLES," Dutch director Vincent Monnikendam's absorbing and often poetic portrait of the storied Italian city, will have its American premiere today at the National Gallery of Art. The 94-minute film examines the historical relationship between Naples's aristocracy and the poor, a complicated matrix of noblesse oblige, condescension, mutual dependence and denial. Eavesdropping as Neapolitans gossip, flirt, argue, philosophize and work, Monnikendam does for this troubled, beautiful city much what Robert Young did for Sicily in his influential 1961 film "Cortile Cascino." "Souls of Naples," though, has the added advantage of having two compelling offstage characters in the form of Mount Vesuvius and Caravaggio, whose influences -- one physical, one spiritual -- are felt in almost every aspect of Naples's daily life.

GET A MOVE ON, hon. Today is your last chance to catch the Kennedy Center engagement of "Hairspray," the musical that imagines early-1960s Baltimore as a place where a big-haired big girl, Tracy Turnblad (Keala Settle), can win the man of her dreams and bring about racial harmony by leading the charge to integrate a TV dance show. "Hairspray" retains some of the subversiveness of the 1988 John Waters film on which it's based (Divine's drag portrayal of Tracy's mom, Edna, for example, inspired the casting of Harvey Fierstein in the musical's original Broadway cast and John Pinette in the current touring company). And the score by Marc Shaiman and Scott Wittman sparkles with some of the catchiest tunes you'll find this side of a Charm City jukebox.
