I have found a link for Psy-war from Costa Rica. It's an old Doom/Death demo tape, ripped with a good quality, but I have problems for downloading from Zshare. I will be thankful if someone download it from this link

http://www.zshare.net/download/19974875aa5c9b5b/

and re-upload it on ifolder.ru or megaupload.com. Thanks in advance.
