you should probably go to grand buffet's bandcamp, cuz thats where to buy music from them these days
if you're looking for the other guys that were on the old pureuphonic site, you should probably start with their new store thing but that's kinda barebones or their facebook right here but like they don't do much anymore
and here's a link to the archive.org version of their site with the last updates, which maybe that's what you want last posts from 2009 but it was last modified 2011 so idk
