For all I know, you guys are already bombarded with thousands of fan letters every day! Why add to the weight with potentially mediocre Metal?
I generally tell people about the DLA, deathmetal.org, and hessian.org, and some of the other related sites which may be relevant to their interests. As it is, most of the guys I know are Black Metal musicians, zine writers, label/distro runners, and a couple of artists who do logos and/or cover art. Pretty much all of them are focused on Black Metal rather than Death Metal, but I suppose it's all "extreme Metal". I'll see if anyone's got any real idea of what's going on in their street/village/town/city/province/country.
