Scullers Jazz Club has moved into a larger downstairs room at Hilton’s Double Tree Suites hotel on the Charles River that’s designed with clear two-tiered sight lines and a new sound system, and alto saxman Maceo Parker—who flexed his funky chops with James Brown, P-Funk and Prince—holds court there on Friday. But other shows of note share the night. Husband/wife Americana duo Shovels & Rope continue to shake up their sound on new album Little Seeds and support it with a show at House of Blues, Canada’s punky power-pop quartet Sloan rock the Brighton Music Hall, fado singer Mariza plays her first Boston show since 2009 at the Berklee Performance Center, and New Orleans’ falsetto crooner Aaron Neville charms in a duo setting with keyboardist Michael Goods at the Cabot in Beverly.

Reggae-steeped Dub Apocalypse and blues belter Julie Rhodes’ band highlight an outdoor music festival at Union Street watering hole Bull McCabes late Saturday afternoon and evening, while the Motet continues the groove that night with its Denver-honed mix of funk, jazz and Afrobeat at the Paradise Rock Club.

Sunday turns out to be the weekend’s biggest music night, including an all-star song swap to draw attention to the global refugee crisis, with Emmylou Harris joining Steve Earle, Buddy Miller, the Milk Carton Kids and special guest Robert Plant at the Berklee Performance Center as part of their 11-date Lampedusa: Concerts for Refugees. Likewise, jazz fusion fans can rejoice when Chick Corea reactivates his late ’80s Elektric Band (featuring drummer Dave Weckl, bassist John Patitucci, guitarist Frank Gimbale and saxophonist Eric Marienthal) at the Wilbur Theatre.

Wales’ brassy indie-rockers Catfish and the Bottlemen also raise the roof at House of Blues on Sunday, though the night’s most intriguing double bill hits the Sinclair with Berklee-bred, New York-based singer/songwriter Margaret Glaspy (pictured) and Ellen Kempner’s Boston indie-rockers Palehound. Glaspy’s broad emotional and sonic sweep, ranging from influences like Elliott Smith and Joni Mitchell to grungy echoes of PJ Harvey and Weezer, quietly put her debut Emotions and Math into consideration among 2016’s best albums.
