I'm with Unregistered, Overkill's DVD is AWESOME. Judas Priest's new "Live In London" DVD is pretty badass, with some great vocals by Ripper on rarely played songs. I personally love Metallica "Live Shit" DVD, especially the second disk: Blackened, ...And Justice For All, The Thing That Should Not Be, the full version of Master of Puppets, and other rarities live and kickass. It's worth a look if you've got fifty bucks, since the CDs are great too.
