You're right, it's a mystery how anybody could not smile at all... But not everybody kept it! It might not being seen, but a few people - including me - was smiling, even laughing sometimes! You're really right - funny, how snobism not let people do what they feel like just because it's a concert situation. I hardly even call this a "concert". I think it's a performance focused on sounds. Or what :D - it's brillint in my opinion.
