French website La Blogothèque, alongside Converse, have an “Empty Space” video series where they film bands performing in these epic empty spaces around Paris. The latest features Sigur Rós, who take to an underground cave to perform their Kveikur cut, “Hrafntinna.” It may seem like an unlikely setting but as you watch the video, it’s undeniable how perfect it becomes for a song as lush and cinematic as “Hrafntinna.” Watch the incredible performance above.
