Is it recent? (I don't follow Gackt's releases) LejuN, the guy who owns the site, has had a lot going on so he hasn't been able to keep -scape-'s news and discographies updated. So either it was an oversight, or he hasn't had the time to add it yet.
As Navate said, I have not been making updates to the sites as of recent. I would like to eventually at least keep the discograpgy sections going, but as of now, I don't see where I can find the time.
