It’s a bustling, high-profile period for Lukas Nelson (pictured) and the Promise of the Real. The California band joins Friday’s Outlaw Music Festival at Mansfield’s Xfinity Center on a Friday bill that includes Sturgill Simpson, Nathaniel Rateliff & the Night Sweats and Margo Price as well as his headlining father Willie Nelson. The Promise of the Real then performs with Neil Young as well as on its own at Saturday’s Farm Aid concert at the Xfinity Theatre in Hartford, Conn., joining Dave Matthews (with Tim Reynolds) and John Mellencamp as well as the same principals from the Outlaw Music Fest. Finally, Young joins the Outlaw fest at upstate New York’s Saratoga Performing Arts Center on Sunday. October won’t slow down for Lukas Nelson by the way, with the release of the film remake of “A Star is Born,” in which the Promise of the Real serves as the backing band for Bradley Cooper and Lady Gaga, who co-wrote songs with Nelson for the soundtrack.

Friday’s also jamming on the Boston waterfront with hometown heroes Dispatch at Blue Hills Bank Pavilion, while Chelsea-born piano icon Chick Corea continues his trio stand at Scullers Jazz Club on Friday through Sunday. The weekend also offers the last three nights of Bust Out Boston, a celebration of female-identifying musicians that hits the backroom of the Burren in Somerville with local acts that include Petty Morals, Mint Green, the Devil’s Twins, Megan Tracy, Oompa, Carissa Johnson, Shepherdess and Melissa Ferrick. Here’s the Bust Out Boston rundown.

Butch Walker — who’s made his name in pop-punk circles and beyond as a well-respected and versatile singer, songwriter and producer – also plays Royale on Saturday, while witty and seasoned singer/songwriter and Berklee professor Livingston Taylor rolls into City Winery the same night. The Cabot in Beverly remains busy as well on Saturday with solo artist and longtime Springsteen sideman Nils Lofgren in an acoustic duo and on Sunday with groundbreaking punk-folk singer/songwriter and feminist activist Ani DiFranco and her band.

Sunday’s shaping up as a glorious day with Jazz on the Charles, a free afternoon Celebrity Series event where 25 local jazz combos — including the Tim Ray Trio, Charlie Kohlhase’s Explorers Quintet, the Yoron Israel Connection, the Jason Palmer Quintet and Funkacademy – interpret a Ken Field-curated list of Boston-related tunes in their various ways. Here’s the scoop on Jazz on the Charles. And over in Somerville at 3 p.m., under-sung singer/songwriter Thea Hopkins performs during a free CD release party at Arts at the Armory. And Sunday night comes alive at Blue Hills Bank Pavilion with the Northwest-hatched Portugal. The Man (bound to surround hit “Feel It Still” with sensory overload in the vein of the Flaming Lips) as well as Lucius, the Berklee-born art-pop duo of Jess Wolfe and Holly Laessig whose harmonic convergence make it imperative to show up for the opening set.
