The first ever rave inside of a glacier is happening this summer in Iceland as part of Secret Solstice, a festival that takes place during the region’s annual summer solstice welcoming 24 hours of sunshine. The only catch is you’ll have to be one of 70 lucky people chosen to attend the “Ice Rave.”

The festival itself features some awesome acts like Wu-Tang Clan, FKA Twigs, The Wailers and Charles Bradley, while Totally Enormous Extinct Dinosaurs and Artwork will throw down in the offsite glacier. In order to have a shot at the ice rave, attendees must first purchase a ticket to the festival as well as a pass to the ice rave.

Langjökull is Europe’s second largest glacier, and it’s accessed using ice-traversing vehicles previously used by NASA to transport rocket equipment. For the 70 attendees, a guided tour of the cave ends in a full-blown dance party in a man-made tunnel underneath the ice.

Secret Solstice Festival takes place June 19-21 with the ice rave going down on the 20th. You can get tickets for the ice rave here.
