Xenocide was a print and electronic Death and Thrash metal zine that I produced in 1992 and 1993. The info below is HIGHLY out of date, so beware!
Here are all five issues in text format. Issues 4 and 5 also had more elaborate printed layouts with images. I don't have any of those available other than my personal copies, and it would be a huge pain in the ass to scan them.
The one interview that I really liked was in 1992 with Type O Negative. I have put it on its own page here.
About Adam Gadahn - Yes, the Adam Gadahn that contributed to issue 5 is the same one that is currently wanted for questioning by the FBI, among a group of seven terror suspects announced in May 2004. I do not personally know him or where he is. Back in 1993, he emailed me reviews and we exchanged email and paper mail. This was before he converted to Islam and allegedly went sideways and became a jihadist. No, I don't think it was the fault of heavy metal. Anyway, his reviews are in issue 5, so you decide.
