CROTON-ON-HUDSON, N.Y. - Let’s face it, it almost doesn’t matter who’s playing at Clearwater’s annual Great Hudson River Revival, which takes place every Father’s Day weekend in Westchester County’s sparkling Croton Point Park on the Hudson.

The star of the show this year, as every year, is the river itself — and one of the most beautiful, breathtaking settings for any festival anywhere, this year celebrating its 35th year.

That said, this year’s lineup is equally dazzling, led by gospel and soul icon Mavis Staples, David Bromberg, acoustic Hot Tuna, Kris Kristofferson, Brooklyn’s Sharon Jones and the Dap-Kings, Judy Collins, the late Levon Helm’s Dirt Farmer Band and Sierra Leone’s Refugee All Stars.

There’s Guy Davis, David Amram and Tom Chapin, Ivan Neville’s Dumpstaphunk, Toshi Reagon, Susan Werner and The Klezmatics, Terrance Simien and the Zydeco Experience, David Broza and a special tribute to the late Richie Havens.

Then there’s The Last Bison, Son Volt, Patterson Hood and Jason Isbell of the Drive By Truckers, The Lone Bellow, collaborations between Hot Tuna and Steve Kimock and Keller Williams and The Travelin’ McCourys and plenty of international-flavored bands, including Afrobeat-fueled Antibalas, Bhangra-based Red Baraat, Malian “desert blues” from Vieux Farka Touré and Celtic-Asian fusion from Delhi 2 Dublin.

Looking for something more deeply American? Native-American artists include Buffy Sainte-Marie, Joanne Shenandoah and roots-soul vocalist Martha Redbone.

Oh, and then there’s festival co-founder and American folk music living legend — and activist — Pete Seeger, 93. And that’s just a sampling.

Tickets and more information are available at www.clearwaterfestival.org or by calling 845-236-5596.

“Pete Seeger is coming back to perform this year” after one year without officially being in the lineup, said festival director Steve Lurie, president of Music Without Borders.

The largely bio diesel- and solar-powered Clearwater Festival, as it is commonly known, has always been just as much about the river, the environment and activism as it has been about music.
