The Black Keys have cancelled their scheduled appearance at Woodstock anniversary festival Woodstock 50 in August. In a statement, they say, "due to a scheduling conflict, The Black Keys will unfortunately need to cancel their set at Woodstock. The band wants to let fans know as soon as possible and before tickets go on sale."

Tickets to Woodstock 50 are set to go on sale on Earth Day, April 22. The festival has yet to release a statement about the cancellation or announce a replacement act; stay tuned for more information.

The Black Keys released their first song in five years, "Lo/Hi," early in March, and have since announced a big tour with Modest Mouse, the "Let's Rock" tour. That tour starts with a headlining slot at Las Vegas festival Life is Beautiful, which hasn't shared the rest of its lineup yet, and also includes a show at Brooklyn's Barclays Center on October 15 (tickets).
