I suppose this goes here, despite being "magazines" proper... they seem to be more "anime" related.
LisAni! 8.1An iM@S special issue, previously the 5.1 issue from back in June of last year was also an iM@S special. Preorder at CDJapan "sold out" after I ordered, but considering 5.1 is still in stock they should have plenty by the time of release. Includes interviews, talk tracks, all that good stuff.
Precious Album (Artbook)
That's the only merchant I bothered to find with images of it. I did find a blog with a G4U!-on-paper
Iori collage from the book! I imagine this has plenty of other content as well, given the classification. Act quickly if interested,
CDJapan had two left after I ordered. They may restock in the future, though I wouldn't have any idea as to when.
Gakken Marketing: Visual Collection (Artbook)
I'm not terribly familiar with their visual collections, though I am aware they publish Megami Magazine. CDJapan has some info on it, though it's listed as "Part 1." So it may imply a second volume down the line somewhere, or perhaps simply a listing error? Either way I dig it. CDJapan wants preorders by the 17th, so a few days left as of this posting.
AmiAmi also has it listed, although it's under a "provisional" preorder status.
Unrelated to the anime, but I'm excited for it anyway, the latest
STATION!!! radio CD's info has been revealed. This time with a vocal version of "HEART AND SOUL" included, which is quite groovy itself.
