• First and foremost, I highly recommend the Wikipedia and sites related to Heavy Metal and its subgenres.  I have relied quite a bit on these excellent resources, and I link to them frequently throughout this site.
  • If you're interested in sampling some of this music, YouTube is a helpful site (particularly the Disco feature), as many (if not all) of the tracks I reference have a video available (although not necessarily as a static link, alas).  Grooveshark is another excellent online streaming site with many of these tracks.
  • I also can't say enough good things about the documentary Metal:  A Headbanger's Journey.  Find a way to watch this if you're at all interested in Heavy Metal Music!
