DISCONNECTED just released their ISOLATED demotape which you can get as physical copy from SONIC SEPPUKU PROJECTS and download as an mp3 rip from their bassplayer's blog NOTHING WHEEL and also from this blog here soon(er or later)!
DISCONNECTED play HARDCORE which is influenced by BLACK METAL quite a bit! the demo comes with a printed cover and has some great artwork including the brilliant slogan: OUR PUNK IS NOT YOUR PUNK! I'd recomend you buy the tape cause the vocals sound way better on the tape than they do in the mp3 version!
* I'm well aware that Sean's blog has the same name but he was kind enough to suggest to use that name for the series as well!
