linked me to Kaede's official site, so I investigated a bit and found some pictures and other stuff about him.
The biography on his official site is a bit confusing, but he's been in at least FATBUG and LastConversation before THE GALLO, and it looks like he's still in test-No. with two former members of BY-SEXUAL.
Apparently he's also done freelance/support drumming and played on the CDs of several bands, such as PRIMEADDICT and Watashimeslug and a bunch of other bands not in the visual kei scene (I think). He also took part on LM.C's LA tour.
You can listen to LastConversation on their MySpace
, and test-No. on their MySpace
Personally I don't like LastConversation at all, but test-No. sounds a little better. :D It seems like he's more into other genres than visual kei (not that the other members aren't, but they haven't been in any non-visual bands as far as I know), but I do hope THE GALLO will be more like THE SKULL FUCK REVOLVERS than Kaede's old bands. Haha.
Overall it seems like he's pretty experienced, he's been in the scene since 2001 (much longer than the TSFR members!) and played with some pretty cool bands and people.
