Yes, some of these favorite bands from each country will also be featured in my 100 Favorite Bands Series, so there will be some repeats.
Well I think most long-time readers would be able to guess that my favorite metal band from Australia is Destroyer 666, the incredible war metal band. D666 mixes black, death, and thrash metal into a sound that brings to mind the soundtrack for an extremely brutal battle, hence the name of the genre.

Australia of course has the whole "war metal" scene down to a science.
