Ever wonder what it would be like if baby talk could become a whole band? Wonder no longer, friends, because it already happened. Some of you already know who Sigur Rós is. (Or, really, at this point, "was.") The rest of you are going to think Mark and Tyler are entirely fabricating this band from their imaginations. Defying all logic, this was a real thing. In fact, it was a cult and nearly everyone between the ages of 35 - 45 knows at least one person who was in this cult, whether they'd admit it or not. Some of them still have the tattoos. WARNING: this is the closest Mark's head has ever come to exploding while recording an episode. Press play at your own risk... of laughing your ass off.
