Woodstock 50 festival organizers have postponed the initial ticket on-sale, which was originally scheduled to go on sale this Monday, April 22nd, in honor of Earth Day. The three-day festival is set to take place from August 16th–18th in Watkins Glen, NY.

As Billboard reports, booking agents were informed of the ticketing delay on Friday. “There is currently a hold on the Woodstock 50 on-sale date,” Woodstock talent manager Amanda Phelan wrote in an email. “We are waiting on an official press statement from Woodstock 50 regarding updated announce, ticket pricing, and overall festival information. We will get this information to you as soon as we receive it.”

Billboard also included a quote from a concerned booking agent, who explained, “No one knows what the hell is going on but there is clearly a problem.” The agent speculated that there could be an issue with investors or the festival grounds, Watkins Glen International Speedway.

Last Friday, The Black Keys announced that they will no longer be a part of the Woodstock 50 festival, sparking worry and fear of a full cancellation of the 50th celebration of Woodstock’s iconic event, with the recent ticketing debacle.

Woodstock 50 promotor Michael Lang spoke to Billboard about the stated concerns. He explained, “Woodstock is a phenomenon that for fifty years has drawn attention to its principles and also the rumors that can be attached to that attention.” Lang went on to say that chatter surrounding the festival’s cancellation are, “just more rumors.”

Artists scheduled to perform on day one of the festival on August 16th include The Killers, Miley Cyrus, Santana, The Lumineers, The Raconteurs, Robert Plant and The Sensational Space Shifter, Nathaniel Rateliff & The Night Sweats, John Fogerty, Run The Jewels, The Head and The Heart, Maggie Rogers, Michael Franti & Spearhead, Bishop Briggs, Anderson East, Dorothy, Larkin Poe, and more.

The Man, Gary Clark Jr., Edward Sharpe and The Magnetic Zeroes, David Crosby and Friends, Dawes, Margo Price, Nahko and Medicine for the People, Jade Bird, Country Joe McDonald, Emily King, Soccer Mommy, Taylor Bennett, Amy Helm, and more.
