The third edition of the three-day festival will take place in June next year.
This will be the third edition of the event, which makes the most of Iceland's striking natural surroundings and round the clock sunlight. The first batch of names pulls together a mix of local and international acts, with Kerri Chandler, Deetron, Will Saul, Benoit & Sergio, Maxxi Soundsystem, Youandewan, Droog and Stephane Ghenacia joining hip-hop star Herra Hnetusmjör, Gus Gus's Högni Egilsson and others. More than 100 names are still TBA.
In addition to the main event, Secret Solstice will also be running an event called Icerave inside Europe's second largest glacier, and Midnight Sun, a boat party where revellers dance to "eclectic DJ sets in a volcano-powered geothermal pool."
