Indie-rockstars of The Black Keys were set to make an appearance at the 50-year anniversary of Woodstock this August, but due to an unspecified “scheduling conflict,” the band will no longer be performing at the highly-anticipated event.

“Due to a scheduling conflict, The Black Keys will unfortunately need to cancel their set at Woodstock,” the duo’s publicist said in a statement. “The band wants to let fans know as soon as possible and before tickets go on sale.”

Woodstock 50, which will commemorate the legendary 1969 festival, is set to run from Friday, August 16 through Sunday, August 18 in Upstate New York at Watkins Glen International Speedway. The Black Keys were slated to perform on Saturday, August 17 alongside acts like Dead & Company, Chance The Rapper, Sturghill Simpson, and Greta Van Fleet. At this time, no replacement act has been announced.

The Black Keys returned to the music scene after nearly five years last month with an undeniably catchy new single “Lo/Hi.” The single is the first from their forthcoming record, which will follow 2014’s Turn Blue. They also revealed the 31-date “Let’s Rock Tour,” which will kick-off in September and run through November, as well as an appearance at Lollapalooza.
