This Weekend's Top Picks
This Weekend's Top Picks in Islip: Jersey Boys at CM Performing Arts Center (Saturday); 2U: The World's Second Best U2 Tribute Band at CM Performing Arts Center (Sunday 7:30PM).
Saturday, April 18 | Time not confirmed | CM Performing Arts Center, Oakdale | $$
The story of Frankie Valli and the Four Seasons comes to Oakdale this weekend as CM PAC launches a month-long run of the smash jukebox musical. Jersey Boys traces four guys from Newark through doo-wop, fame, fractures, and a catalog of songs that never left the radio. CM PAC's stage has a way of making Broadway-caliber productions feel personal, like you're watching the rise from a front-row seat in the old neighborhood. This one runs through mid-May, but opening weekend carries its own charge.
Sunday, April 19, 7:30PM | CM Performing Arts Center, Oakdale
They lean right into the name, and that self-awareness is part of what makes 2U work. Sunday night at CM PAC in Oakdale, this tribute band runs through the U2 catalog with the kind of commitment that fills a theatre on a school night. From "Where the Streets Have No Name" to "One," the setlist covers the stadium anthems and the deep cuts. A strong way to close out the weekend.
For Families
For Families in Islip this weekend: Don't Let The Pigeon Drive The Bus at CM Performing Arts Center (Saturday); Nick the Balloonatic at Islip Public Library (Saturday 11:00AM).
Saturday, April 18 | Time not confirmed | CM Performing Arts Center, Oakdale | $$
Mo Willems' stubborn, scheming, totally lovable pigeon jumps off the page and onto the CM PAC stage this weekend. Kids who've spent bedtime negotiating alongside that bird are going to lose it when they see the story play out live, complete with all the dramatic pleading. Parents, you already know how this one goes. An easy yes for the whole family.
Saturday, April 18, 11:00AM | Islip Public Library | Free
Nick the Balloonatic turns a Saturday morning library visit into a high-octane, hands-on balloon-twisting show that keeps kids locked in from start to finish. The Islip Library hosts, and the format is perfect for families with younger kids who need something interactive that runs on pure fun. Get there early, because these fill up.
