Iceland's Secret Solstice festival has a huge lineup of over 177 acts and is set to go down this weekend. But Deftones' Chino Moreno may have the most anticipated set as he's slated to play the festival's Inside The Volcano show which means he'll touch the stage 400 feet inside an actual volcano, marking the first time that has ever happened.

The guests will be lowered into the volcano's dormant magma chamber. The festival says there's little chance the volcano could erupt as it hasn't for 4,000 years, according to geologists.
