It’s (almost) all about Boston Calling this Memorial Day Weekend as the rock festival move into its huge, grassy new digs at Harvard’s Athletic Complex in Allston with a bump to three stages plus an added comedy stage hosted by Hannibal Buress.

Friday mixes it up with hip-hop trio Migos (replacing Solange, a late scratch for “production delays and complications beyond her control”), the gospel-fueled rapper Chance the Rapper, atmosphere-brewers Bon Iver (pictured) and Sigur Rós, electro-pop duo Sylvan Esso, and indie-rockers Car Seat Headrest, Lucy Dacus (who plays an after show at Great Scott on Friday) and Whitney, who have an after-show at the Sinclair on Sunday. Saturday offers hip-hop (including Boston’s own Cousin Stizz), cool Brits in the xx and dance-pop rockers the 1975, synth-pop sisters Tegan & Sara, and a bit of rousing roots music in Nathaniel Rateliff & the Night Sweats, Brandi Carlile and more streamlined headliners Mumford & Sons. Sunday’s finale looms with the highly anticipated return of metallic gloom-prog purveyors Tool as well as an undercard that includes the ironic rockers Weezer, hip-hop firebrands Run the Jewels, frank pop upstart Mitski and more Boston love to rockers Buffalo Tom, Piebald (who play Saturday’s Sinclair after-show) and the Hotelier. Here’s a link to Boston Calling info as well as the whole schedule.

On a different note, you can check out great trumpeters at Scullers Jazz Club on Friday with Nicholas Payton’s Afro-Caribbean Mixtape and on Saturday with the Sean Jones Quintet, sporting the ex-leader of the Jazz at Lincoln Center Orchestra.
