The Hobbs 'n Harbal show is about the power, or not, of symbolism. I see anthems as symptoms and the "disease" is patriotism. I live not far from a prestigious private school with beautiful grounds. At one stage I dated a lefty who, when I suggested a walk in those grounds, spent the entire time in apoplexy at the injustice of this school having so much while so many are deprived. He was right too; it was obscene. Nonetheless, those grounds are beautiful to walk around and the school has a rates reduction deal with the council to allow public access. Great for walking the dog too.
Still, this scrupulousness can be taken to whatever level suits an individual. I also once dated an experimental artist and writer who harshly judged music with lead voices and band hierarchies that represented the hierarchic nature of society. Experimental artists also routinely subvert the usual artistic structures deemed valuable by the elites. Marxism is very common in the experimental music field, almost to the point of cliche.
When I attend gigs, I am aware of the hierarchic structures and the metaphysical relationship that has with broader society, but I simply don't care. Deep as a puddle, I am
So I reject anthems on mostly aesthetic grounds, which I class with dull military music. Music of the unthinking masses that the establishment prefers. Yet, if the sound and style of the music made my ears happy, I'm sure I'd find a rationalisation for liking it.
