Ultimately, to insist that rock criticism be political is first to insist that the humans who make and enjoy music are embroiled in politics whether they like it or not - and whether they know it or not.
People believe that criticism should be objective, whatever that means, but I really don't understand what people mean by that. I guess if you're doing sonata-allegro procedure analysis, you can be objective for a page or two. But in pop? Really hard.
Subject is very important. If you're going to write non-fiction the style means nothing or very little. The content justifies the effort you need to put into the writing itself.
If you wanna write non-fiction you have to be interested in the world.
I believe that writing on music is experienced inside your head, is not a physically present in the world, it has a different kind of authority and prominence and you absorb it differently.
I don't believe in pulling punches or being judicious, as the standard in literary criticism or academic musicology.
