End of the Rainbow Festival, which was set for Labor Day Weekend this year at The Gorge Amphitheatre in George, WA—and considered to be something of a replacement for the annual Sasquatch! gathering that called it quits last summer—has been postponed indefinitely, according to the event’s organizers.

As Dance Music Northwest reported, fans who had purchased tickets to End of the Rainbow received an email on Friday from Ticketmaster announcing the postponement, citing “unforeseen complications and key artist cancellations.”

The statement also says that all tickets will be refunded “promptly” and that they are attempting to reschedule the event.

Read the full note below:

“End Of The Rainbow event, planned for Friday, May 24th through Sunday, May 26th at the Gorge Amphitheatre, has been postponed indefinitely with an undetermined date. Your original tickets will not be honored for the new date if rescheduled.

End of the Rainbow was built on a desire to create a special event for all attendees at The Gorge. Due to unforeseen complications and key artist cancellations, we have been forced to reschedule. We will promptly refund all tickets & shuttle accommodations while we work to schedule a new date.
