Three Hands Of Truth - Dead Kelly.
(Dead Kelly are due to release some more music soon. Like all their stuff it will be free from their website and their three fingered guitarist really has learnt how to master his axe with a missing index finger.)
Three chords is all you need to play metal It's interesting to hear the guy play now, he put in quite a bit of effort to teach himself to play without an index finger. Initially the difference was obvious but as time goes on it's getting less and less so.
