It’s Labor Day weekend – and (almost) the last chance for festivals, from annual multi-day events like Rhode Island’s Rhythm & Roots and Club Passim’s Campfire to Saturday’s Rock the Roots on City Hall Plaza and the Newburyport Riverfront Music Festival. Plus assorted offshoots and the return of Pearl Jam to Fenway.

Rhythm & Roots brings zydeco, Cajun, country, blues and roots-rock to multiple stages at Ninigret Park in Charlestown, R.I., with Steve Earle (pictured) and the Dukes, the Taj Mahal Trio, Leftover Salmon, Asleep at the Wheel, Hot Rize, Donna the Buffalo, Dustbowl Revival, Steve Riley & the Mamou Playboys, CJ Chenier & the Red Hot Louisiana Band, Session Americana and many others. Here’s the Rhythm & Roots schedule. Leftover Salmon also play the Cabot in Beverly on Friday before hitting Saturday’s festival, while Steve Earle and the Dukes headline Rhythm & Roots on Friday before moving to Prescott Park in Portsmouth, N.H., for its free series, which also sports Americana duo Shovels & Rope on Friday.

Club Passim’s 20^th annual Campfire Festival keeps patrons flowing in and out of the historic Harvard Square coffeehouse to see such performers as Jim Infantino, Dave Godowsky, Rose Polenzani, David Champagne, Future Teens, Walter Sickert & the Army of Broken Toys, Lloyd Thayer and Annabelle Lord-Patey. Here’s the Campfire rundown. City Hall Plaza rocks Saturday afternoon with a Rock the Roots lineup including California rockers Young the Giant and Boston’s prime hip-hop crew STL GLD, while Newburyport comes alive with 92.5 the River’s annual free Riverfront festival, featuring the Barenaked Ladies, Phillip Phillips and Anderson East. Meanwhile, the Aaron Neville Duo performs at the Cabot on Saturday. And then the weekend’s big show arrives on Sunday with Pearl Jam invading Fenway Park to pay homage to rock, baseball and anything else that singer Eddie Vedder and company want to point out – before they do it again on Tuesday.
