Part 1 of 13
And
here is the gallery with all three musicals, broken into three parts.
Aside form a couple songs, these aren't subtitled. But if you're at all familiar with the series, it should be easy to follow. The songs are quiet catchy and it takes a minimalist approach with the props, mostly relying on creative use of lighting. (The battle with the Menos and Byakuya's total pwnage of Ichigo are good examples of this.)
SPOILERS!
The first two start with the Karakura Town Arc, quickly introducing you to Ichigo, Rukia, Orihime, and Chad. (Ishida is conspicuously absent, though he is mentioned in passing.) They then move onto the Soul Society Arc, severely condensed and ending with the rematch between Ichigo and Renji.
Saien is basically a bigger budget version of the original, with a few new songs and the addition of Kira.
Dark of the Bleeding Moon finishes the Soul Society Arc, with more characters to boot (Yoruichi, Hanatarou, Matsumoto, Ikkaku, and Zaraki).
