For all of you who have been in a choral or musical group of some kind this is your answer to how you would do it differently if in charge. Watch it all even though it is in German with subtitles and a bit long, it is brilliant.
As one of the comments says, "German is the best language for raging." Even when you don't read the English translation is sounds so cool.
It is also suggested that this would be a fun thing to do with a choir performance. Well what do you think singers?
