If you don't know who they are, they you suck. I'm kidding. Even if you do know them, you still may suck...i don't know.
But that is besides the point. They are a Japanese shoegaze/j-rock/experimental band that has been around for 17 years. They have an extensive catalog that spans 18 albums, most of which are EP's.
Here is some more info on them:

The greatest thing about them, is that every album sounds different, at times almost to the point of asking yourself "is this the same band?". One album may be all dream-pop and the next one may be death-metal/thrash-metal/shoegaze. Another maybe be downtempo/j-pop...you never would know until you got the album itself.
So, with no further a due, here is the full COTD catalog minus one 2-song EP that i cant find. Enjoy!
