Would Metal bands would you consider Avant-Garde?
I don't really think I'd say they're "avant-garde". Their stuff isn't really diverse enough.

Well, "avant-garde" doesn't really have a set in stone meaning, so it will mean different things to different people. When I think of something that's avant-garde, I usually think of bands that have albums that are totally different from each other. While Gorguts experiments with a lot of stuff, it's all still Tech Death to some degree.
