I don't have much information around this demo. I picked it up somewhere while in Japan in 2003. Neoteny (or is it Neoteny64. I don't know) run with the Tokyo screamo crowd and did a split with Egoist for Men. I found the video below, and I totally dig the song. They play that Japanese emotional hardcore sound without being derivative. The demo has keyboards and a slight Gauge Means Nothing feel to it. There's no insert to the demo, so I don't know what the songs are called. But, they are great. Check it out and enjoy!
