What conditions allow for quality metal/anything to be produced?
A stronger awareness and attitude that has been developing in underground that marks a return to values centered around quality as opposed to "anything goes", adherence to tradition while avoiding stagnation, desire for genuine expression, reexamination of our roots, present, and future, and so on.
This attitude can be found in many bands, some new and others not so new, some with a simpler approach, and others treading more obscure pathways, but all, to my mind, true to the values of metal with the guns to back it up. I'm thinking of projects like (if anything on this list offends you, feel free to engage in healthy debate about it, or go whine in the corner while the rest of us engage with the real world): Averse Sefira, Beherit, Asphyx, Graveland, Midnight Odyssey, Autopsy, Diocletian, Birth A.D., Weapon, Winterwolf, Grave Miasma, Immolation, Demilich (who are going to be continuing on under a new moniker), Profanatica, Master, Triptykon, Watain, Goreaphobia, Disma, Vader, Dead Congregation, War Master, Blaspherian, Necros Christos, Black Funeral, and, without any doubt, others that do not spring to mind immediately and even more that I am not yet familiar with.
Before the fingers start pointing, I am not arguing that all of these bands are creating truly great work, although I certainly would argue that some are. Few bands ever have or will put out a Pure Holocaust, and the for the one's that do it's a rare event, but what these bands have done is contributed works of notable quality, that are important by their own merits and/or by the fertile ground that they have created for future bands to grow from.
Now: What conditions dissalow for quality metal / "anything" to be produced?
