On October 17, Amazon Web Services announced Intersect Music Festival, which takes place in Las Vegas on December 6 and 7. The lineup includes Foo Fighters, Beck, Kacey Musgraves, Anderson .Paak, and many more. The Black Madonna is also featured on the lineup, and, on October 18, she expressed outrage over Amazon’s involvement in the event.

She wrote that Amazon was not listed on any of the festival’s initial offers or paperwork that she received. “What the fuck is this Amazon shit,” she wrote. “I absolutely did not agree to this. Oh hell no.” See her tweets below.

On Friday (October 18), a spokesperson for Amazon Web Services shared the following statement with Pitchfork:

Our affiliation of the Intersect Festival is clear in the contract that was signed by Black Madonna’s management team. “Amazon Web Services” was named in the contract five separate times, and throughout creative materials that were reviewed and approved. Regardless, we’ve decided to release her from her contractual obligation.

The Black Madonna continued to tweet about Intersect Festival. “I never saw the branding for this until my name was attached,” she wrote Friday. “There are 100000000 festivals. I don’t read all their announcements.” Find more of her tweets below.

Also on Friday, Japanese Breakfast, who is on the Intersect bill, commented on the festival. “Everyone has the right to be upset,” she wrote. “I will say like The Black Madonna it was not brought to my attention this was an AWS event.” Find her tweets below.

On Saturday morning (October 19), the Black Madonna posted a longer statement reiterating that her contract did not specify Amazon’s involvement, elaborating on her ethical opposition to the company, and playing down any presumed criticism of other artists who choose to remain on the bill.
