the only thing music requires you to act upon is making sounds.
by doing that some individuals succeed in channeling energy inside of them and others, but creating a doctrine or stigma that relies on material things such as violence is a cheap trick IMO.
yeah, for instance, varg killed this guy, therefore his black metal must be really, really good!
music can be an offspring of culture and ideology, but it isn't reliant on such things, music has an independent existence.
