This post of Ju-ken’s was interesting (history through picks!) and gave me more things to throw into google. I know everyone’s worked with everyone else at this point, but I never would have expected to find information about Ju-ken on a By-Sexual fansite (he was in nitro and food (same band, new name) with their drummer for a while). Also, I think the bassist that replaced him in food is the same as the bassist who replaced him in wipe (not technically a replacement since he was only support there); there’ s kanji on the By-Sexual site and romaji and katakana on the wipe site.

Looking at dates and other random information:

Nao and Ju-ken had toured with Kiyoshi in 1997, including the Kiyoshi/Hakuei show/tour (I’m not sure if it was one show or a tour; there’s a tour book for it, though.) Kiyoshi’s support was Punch (g), Juken (b), Cola (k), Nao (dr); Hakuei’s was Kiyoshi (g), Den (b), Cola (k), Nao (dr). Punch was nitro/food’s guitarist; Den was also in By-Sexual and later was in Zigzo and test-no. and is also currently supporting machine (Hakuei and Kiyoshi’s current band).

Nitro formed 1998, became food in 1999, and his last date with food was 2001.05.07; 渡部嘉之 became support bass 2001.05.17; they ended 2001.09. I’ve also seen Nitoro for the first name; the katakana would be ナイトロ for either one.

Ju-ken, Nao, and Punch (along with Hikaru Yoshida) toured as D.I.E.’s support in 1999; Ju-ken toured with him again in 2001.10 (and possibly other times; those are the ones I’ve seen proof of). I keep running across Steve Eto (percussion for Hotei’s recent tour) while looking for related information (did something with D.I.E. later and was in a band with Hikaru Yoshida at some point).

wipe formed 1999.02; Ju-ken was support starting 1999.04, was alternating with the other starting 2000.03, and ワタベヨシユキ/watabe yoshiyuki officially joined wipe for their tour 2000.08; they ended 2001.03 (nothing listed between those dates)

Oblivion Dust – joined as support January 2001, disbanded June 30, 2001

I found a random concert report for BUG’s 2001.12.30 show in 渋谷DeSeO that listed BUG’s members as KYO, FURUTON, 室姫深 with guest 獣犬; according to a fansite, BUG formed in 2001 and their current bassist joined in January 2002.

Other random finds: pages for support members of FAKE? and S.Q.F.

Also, it seems to be generally accepted on the English-language sites that the kanji he uses means “beast-dog”, but none ever have the kanji itself. That fansite had him as 獣犬, which can have that meaning; now that I look more closely, his entry has that as well. I obviously need to spend some quality time with that entry and a dictionary.
