Flawless!
Dude, this is one of my favorite art pieces I've ever seen! I think its strongest point is that it takes its time starting off to becoming more insane. It grows in ridiculousness as it goes on. When I first heard the name "Requiem" I was thinking of the movie "Requiem For A Dream" which was known for its awesome fast paced music. This certainly fit the bill and I love how it changes right before the end. I was expecting sort of a joke to follow, but it simply continued being awesome.
It's songs like this that make you appreciate the existance of instruments like violins. Its tone appears to be one of madness or simply disorder. It has somewhat of a mechanical tone to it as well. The mechanical tone can also shift to become one of technology leading to computers. There is simply a great story to tell here, even though there are no words. It truly gives off the sense that you went on a great journey yourself to make this.
