damn this language barrier
I downloaded this random album the other day, and I am having trouble finding out much about the band. They're called Sakanakushon, and the album is named Night Fishing.
Here's a download link...just press "Free" to download.
Their official site lists this as their second album, but they seem to be pretty well-developed as a band. The album's definitely worth checking out. That link leads to a Japanese site, by the way.
