Boston Calling is about to get “Bad and Boujee” at the very last minute — Migos have been added to the upcoming Memorial Day weekend festival.

But the addition of Migos, who just performed with Katy Perry on SNL, comes at a cost: R&B singer Solange was scheduled to perform on Friday at 6:45 p.m. but has dropped off “due to production delays and complications beyond her control,” states Boston Calling in a release. Migos will perform in that slot on the Boston Calling Green Stage.

Solange addressed the issue in a tweet Thursday evening:

I'm really really sorry/sad about this but I fought hard to only give u my best, & tons of production drama/delays got all up in the way:( https://t.co/sy8rFQ9kCq — solange knowles (@solangeknowles) May 25, 2017

Friday’s slate also features performances by Chance The Rapper, Lucy Dacus, Bon Iver, Mac DeMarco, Sigur Ros, Sylvan Esso, Car Seat Headrest, and more. Set times are below.
