Since we're on the topic of anime openings, just wanted to share my thoughts on this one...
Translated, it means "Melody of the Wild Dance"... the lyrics of the song is not really deep... so I won't dwell on it.. but if you're interested, you can read it here
As for the cinematic style, well, lets say its an interesting approach... firstly the entire clip has an old film look.. very much like sepia on a 35mm film projector.. giving it a unique memory look..
There is also the olden style of overlaying, in which the image is just burned/superimposed into the background, rather then blended... this is seen numerous times in the clip, at first with Aizen, showing the eminent destruction... but in the last part of the clip, from 1:10 onwards, you have an overlay of Ichigo in bankai, upside-down.
Interesting to note, is that, that is the portion on the clip in which, the sequence of events start running backwards, all the way to the start of the anime, with Inoue's brother as a hollow, and the girl spirit he was trying to save at the start.
Not going into spoilers as to what it means, if you keep up with the manga, you'll get the hint. But yeah, interesting how, this opening does away with the usual fight scenes of Ichigo, but still packs the same amount of tension and easter eggs of what is to come... definitely not exactly like your usual opening =3
And on a side note, I love the symbolism of having Inoue with the Tree of Life at 0:42
