I'm new here, so maybe I'm stepping in with both feet...
Anyway, as Közi is active as a solo artist since Malice Mizer right to this present time, there should be a thread for him, too.
His work is my favourite out of all the ex-MM members!
His OHP is http://www.kozi.info
Well, news? In fact there is news! It is suspected that Közi will release a live DVD, Katarushisu (Catharsis), on 14 November. I (and many others!) did see this on the "Store" section of his official site (a small announcement at the bottom of the page). I have just rechecked the site and don't see that anymore, but my current machine doesn't read Japanese script, so possibly it's just playing silly-buggers.
Anyway, I definitely saw it with my very own eyes on his site, and several times! so it's highly possible that this year will see the first ever release of a Közi DVD.
On 17 May this year, Közi released a mini-album Loki n' Roll; this is his latest release. (I made a review of it here: http://www.nipponproject.com/en/review.php?recensione=6
and also a review in French on the same site.)
His forthcoming shows (unfortunately for us, only in Japan) are:
7 October - Harujuku Astro Hall
14 November - Nanba Rockets, Osaka
15 November - Holiday Nagoya
17 November - Shibuya Boxx
The 15 November show in Nagoya is as guest with several other bands including Calmando Qual and The Candy Spooky Theater (I'd kill to see that show! XD)
Details are, of course, on the OHP.
Other activites of Közi since Malice Mizer:
A collaboration with novelist Minako, resulting in his first full album Izayoi no Tsuki.
Work with Haruhiko Ash on his project Eve of Destiny - resulting in the mini-album Nervous and Innocence, which is incredibly difficult to get hold of due to problems with the record company.
Eve of Destiny toured in Europe, Australia and the Phillippines, but haven't toured or released anything for a long time, leading to abounding rumours that they are going to finish, or at least just drift away.
Közi has also been involved in playing bass with a session band called Death Attack Chainsaw. They played a fanclub-only event in Japan in summer 2005. The other members are Kazune (ex-Brain Hacker) on vocals, Shimizu Shin (an old friend of Közi's) on guitar, and Masashi on drums. I don't know whether this is something that Közi is still involved in or whether it was a short-term project only. He's certainly busy!
Personally, I like his music because it is very diverse and original. In fact, I could write a big long essay on why I like it, but I'll spare y'all!
