Next fall It'll be 2 years since I discovered my favorite artist Kajiura-San next to Revo. Also, I would like to know if Fictionjunction Club vols are mostely photos (like Sound Horizon's)?
The one on Tumblr with the archive of pamphlets is me. Four are released each year, one for each season. Each is sixteen pages up from the original twelve. Also each issue has a form to it:
Messages from members (Yuki, Kaori, Yuriko, Keiko, Wakana, and Hikaru. Older issues also have Yuuka)
Pictures, reports, and thoughts from Kalafina/FictionJunction on concerts as well behind the scenes photos of concerts
Behind the scenes photos and thoughts regarding the making of pamphlets
Interview
Kaori's solo career
Ending message from a member of FictionJunction Club (Kaori, Yuriko, Keiko, Wakana, and Hikaru. Older issues also have Yuuka in the rotation)
Sometimes there will be little question and answer sessions that all of them will participate in.
I'd say they're picture heavy, but have a lot of little comments and the interviews balance things out a bit.
I've been interested in the Sound Horizon newsletters, but can't seem to find scans of the whole issues. Someone used to be active that did that, but no longer does it and their links are no longer active. I do know Dreamport comes up in two issues of Salon de Horizon. I've been saving up to get those particular two.
Go ahead and click on the image in my signature for the newsletters.
