GACKT Concerts DVD: If I were to buy..

[bliss10]

my first GACKT concert DVD, which one do you, my lovely friends, recommend?

Personally I'm leaning towards Diabolos as the first purchase. Any objections or alternatives? I mean if you HAD to chose which one first?

Thanks for any suggestions!

EDIT: OK so far from my personal circle of expert advice the list is:

Diabolos
SDSN
RRI
