[Neganega]

One of my favorite bands ever disbanded last year in march/april (can't remember exactly): NEGA

I'll list a number of bands that I know are gone off the top of my head:

meth.
Necro Circus
PERESTROIKA (although that was only side project of NEGA's, so it's not that big of a deal)
the rudie satan park
ReivieЯ
Since1889
UnsraW
Yaminade
BLACK SHIP
CAINS:FEEL
KYOKUTOU GIRL FRIEND (not sure if active or on hiatus..seems like no official site activity since 2012, but I didn't dig around much)
Luzmelt
ºC (REALLY obscure. they only released one maxi single, and I can barely find anything that has to do with them)

Hope the list helps someone. I'm almost positive all these bands are either disbanded or on hiatus, but make sure to correct me if I'm wrong.
