The Music Festival Wizard team has seen some incredible venues in our travels around the world, but nothing quite like the Atlantis Concert For Earth. Held in the middle of the Atlantic on the stunning Azores, the festival takes place inside a three-mile wide volcanic crater. While the volcano may be inactive, the concert inside erupted for a full two days of rockstar conservationists and conservation-minded rockstars all taking the stage in a united purpose. Check out the recap of the event here.
