Graspop Metal Meeting Lineup Leaked?

We’ve been waiting for a while for the announcement of the 2017 lineup of Graspop Metal Meeting. After the confirmation of Rammstein and the recent addition of Deep Purple, we now got the confirmation of Evanescence as the 3rd headliner for the 2017 edition of the festival. But what we also got was a glimpse of a bigger part of the bill, as Opeth posted this image on their facebook page. They were quick to remove it again, but we got the image. Check it out yourself:

Graspop Metal Meeting takes place from the 16th till 18th of June 2017 in Dessel, Belgium.
