I am the co-host of the underground metal radio show, Monday Night Metal Mayhem, on 88.3 FM, The Edge, out of Springfield, IL, and streaming worldwide at www.wqna.org. Check us out on facebook at www.facebook.com/mondaynightmetal. We play death, black, thrash, doom, folk, and power metal, in diminishing order (the stuff listed first is what we tend to play most). Tune in, and send us a request - we're always looking to discover and expose to our audience new underground metal bands. And remember: "no wimps, no false metal".
I also run a blog at www.therealdrmetal.com which I update not nearly often enough, where I discuss and review my many geeky endevours: heavy metal; fantasy and science fiction books, tv, and movies; electronic gadgetry of many types.
