Identify soundtrack of "The imperial history of rise and fall."?

Question

May I ask what the name of the music is?

I want to see if it is possible to find the entire song for this video (which is actually kind of long). I unfortunately do not know any other info about this piece other than that it have existed for at least 10+ years.

Answer 1

The music is a very badly sequenced version of Claude Debussy's Rêverie for piano, written in 1890.

There's a much better version here.
