Meet the shouting men’s choir of Finland. They run in teams of thirty, dress in all black, drink Vodka, and shout in unison. You might hear them performing at the MoMA. You might run into them performing for the President at the White House. But no matter where you encounter this group of Finnish men, nothing can prepare you for the experience of hearing them scream at you. They feed on surprise and have mastered the art of disturbing a crowd. Go on, watch them perform here.
