This series is quite old, and yet no so much; it would seem vintage but it is only an apperance.
The show itself you might say is progressing quite slowly and yet it would seem to be going in its own pace, not slow yet not brief and taken straight to the point. the combination of the music genre of blues and jass along the show, the lack of many flashy events and effects.. it has only made me to think that all of that was meant to make this a monument the these music genre, slow and quiet yet beautiful.
This was defenitely one of the best animes i have ever watched, not the first but absolutely it owns its spot in one of the highest ranking along all of my exprience as an otaku.
