The much-anticipated sale of tickets for this summer’s Woodstock 50 anniversary concerts has been put on hold for now.

Tickets for the three-day festival on 8/16-18 were supposed to be available on Monday. The festival released a statement Thursday, saying: “Woodstock 50 has delayed its on sale while we refine logistical plans.”

The statement adds, “Ticket on sale information will be available through Woodstock.com in the coming days.”

Jay-Z, Dead & Company, and the Killers were announced as headliners of Woodstock 50, commemorating the groundbreaking Woodstock festival.

The festival is set to take place in Watkins Glen, New York, about 115 miles (185 kilometers) northwest of the original site. The event is separate from an anniversary concert planned at the site of the original festival in 1969.
