c'mon y'all. this j-pop/j-rock anime stuff is all well and good if that's what you dig, but nobody's into the huge japanoise/experimental/jazz/rock stuff? some of the world's most cutting edge musicians are from japan. check it:
mono (very cinematic instrumental post-rock, gorgeous gorgeous)
merzbow (harsh noise/experimental/extreme)
fushitsusha/keiji haino (noise/experimental/rock)
Les Rallizes Dénudés (noise/experimental/rock)
ACID MOTHERS TEMPLE (all you classic rock led zeppelin pink floyd dudes better check this out, 1000x more psychedelic than all of that)
Boris (probably my favorite metal/doom band, cool stuff, variety of styles)
GROUND-ZERO/Otomo Yoshihide (great experimental/noise/free jazz)
but the greatest of all of these is a little osaka band known as BOREDOMS!

everyone should hear their albums VISION CREATION NEWSUN and SUPER AE. look those up. essential, mindblowing, avant-garde, everything. you'll never look at rock music the same again.
BOREDOMS!
