Here's a very interesting link just found while looking around for this Adam guy.
This has stories of new moslems from various countries, including Adam's story on the US section.
Looks like this Gadahn freak was a "Death Metal" fan circa 1993...

I read the bio on "Adam" and a few of the others. What I can't figure out is how gullible they are. Religion of peace? Don't they ever watch the news or read the papers?
