The Tomorrowland Festival organizers are probably wishing they were living in Yesterday-Country right about now … ’cause at least then they still had a stage!

The multiday fest in Belgium was set to kick off in just a few short days … but a fire broke out Wednesday and took the whole stage with it — burning down to the scaffolding from one end to the other.

Tons of videos are circulating online right now … capturing massive plumes of smoke billowing into the sky and flames quickly burning across the intricate stage.

It’s unclear at this time how the fire started … but, it left nothing for the artists to perform on — so, we’d be surprised if they decide to somehow go forward with the show.

David Guetta, Martin Garrix, Swedish House Mafia, Steve Aoki, Kaskade and more stars — many of them DJs — were going to flock to the city to perform over the next couple weeks.

Tickets were already sold out, so it’ll be a lot for the organizers to refund … and, we’re sure it may change fans’ travel plans, too.
