These days, "go fly a kite" is no put-down — it's sound advice, as anyone who's spent time on the beach with the world on a string can tell you. This four-day event on Long Beach Island features entries from all over the world flying artist kites, giant inflatable kites, and demonstrating sport-kite flying techniques. "We will have at least 10 national champion kite fliers on our beaches for the festival this year," says local Lisa Willoughby, a local Master Level Sport Kite Pilot. Featured kiters include Australian designer Robert Brasington, and national champion Scott Weider. Events (free for spectators unless noted) include an indoor competition ($2), bol kite races, a display of giant 3-D kites, an art market and bazaar, an illuminated night fly ($2), a kite battle, a kids candy drop, and more. — Michael Harrington

George Stiles and Anthony Drewe's musical adaptation of Hans Christian Andersen's The Ugly Duckling, follows an odd, gawky fowl, teased and bullied by his siblings and farmyard neighbors, on his adventures after he is chased by a cat and becomes lost. On his journey home, he learns what true beauty is, and finds love and acceptance. Always a lesson always worth learning, no matter your age (though this is best for those ages 5 and up). — M.H.

No, not the kind that haunt internet sites and make nasty comments (those trolls need to get a life). This 2016 animated adventure features the wild-haired, snub-nosed, perpetually grinning dolls that have been making kids happy since the 1960s. The story follows the happiest, peppiest troll there ever was as she sets off, accompanied by the bluest, most curmudgeonly troll ever, to save her friends from the clutches of big baddies who only find happiness in squelching others' lives (sound familiar to readers of internet sites). The music is great, as to be expected when a film features the voices of Justin Timberlake and Gwen Stefani. It's got some scary stuff-eats-stuff scenes, though, so it might be best for ages 6 and older. — M.H.

Believe it or not, this is the 166th year for this event — yes, it's been happening since before the Civil War (the church itself dates to 1715). So they've had time to get good at this.

On the bill: The Party, a 1971 episode of the long-running Catholic TV series Insight (from a company run by a Hollywood producer who also happened to be a Paulist priest), starring Meredith Baxter (the Family Ties mom), Joy Bang (the quintessential 1970s hippie-chick actress), and Billy Mumy of Lost in Space fame as a background musician at the shindig; Junior High School, a 1977 featurette about a kid trying to ask a girl to dance, with appearances by a teen Paula Abdul and Dave Frishberg (who wrote "I'm Just a Bill" for Schoolhouse Rock) as a shop teacher; and Revenge of the Nerd, a 1983 episode of CBS's Afternoon Playhouse, in which a computer whiz tries to gain the respect of his classmates. — M.H.

Just pretend the two Vs are one W, and pronounce it "always." (It's also much easier to Google the band this way.) The Toronto quintet is led by Molly Rankin, who grew up in Cape Breton in a leading Canadian Celtic music family but veered away most satisfyingly into deliciously catchy indie-pop. The band gained attention with "Archie, Marry Me" from their 2014 self-titled album and are back in style with their bewitching new follow-up collection Antisocialites. Nova Scotians Nap Eyes open. — D.D.

The last time that Kesha played a full concert in these parts, she was not a free woman, and still known by the cash money moniker, Ke$ha. At that point, she was still stuck under the contractual thumb of producer/label owner Dr. Luke in a tale of alleged abuse (look it up) of which we may never know the true story. No matter. Out now, free and funk Kesha's new Rainbow record finds the singer-songwriter once known for club-pop, New Wave-y rap-rock, doing everything from freak folk and twanging country, to sleek garage rock with a top hop feel and a spiritualist lyrical éclat. Weird but fun. — A.D. Amorosi

On his albums, Sam Amidon seems serious and introspective. He's an experimenter who often resets lyrics from ancient Appalachian folk songs (and the occasional R. Kelly track) to hypnotic, propulsive arrangements for fiddle, banjo or acoustic guitar. On this year's The Following Mountain, Amidon works, for the first time, solely with his own lyrics. Collaborating with free jazz drummer Milton Graves and others, he stretches out the compositions even more. It's fascinating and at times otherworldly. He also guests on the new Kronos Quartet album. During his shows, Amidon interjects humorous, manic anecdotes which contrast, sometimes dramatically, with the intensity of performances. Monday night, he'll play in a trio, with a bassist and electric guitarist. — Steve Klinge
