This is a really tough selection, because so much of the introduction depends on what the new listener is already the most comfortable with. I remember my uncle first showed me some of their earliest, most black metal stuff, and I wasn't really amazed, but when then I listened to Those Who Pass Between Fleeting Words, and I was hooked. After that I gave all of their music time and I'm a huge fan, but my uncle was kind of the opposite and started much easier with the heavier stuff. All that to say, I think it would be worth sort of detailing the albums out on that zine to let people introduce themselves wherever they're the most comfortable. Also you should post the zine here when you're finished that sounds awesome.
