This is one of the most NSFW, gross music videos I've ever seen. On the other hand, it's also the one of the best examples of excellent pixel art animation. Seriously, its great stuff.

But yeah, totally NSFW.

The bands called Anamanaguchi and these guys are simply, great! Who would have thought making awesome music from the NES 8bit audio track would sound so good. I believe they have a record out right now, and since they're still underground you can legally steal there music :] enjoy!
