There's anonymity/pseduonymity where we have a entity that does not do any performances and releases cassettes with members acknowledged as "M., K. and J." or even nothing and there is "anonymity/pseudonymity" where a band tries to use that as its own image (eg Kanonenfieber). Obviously I meant more like the former which is legitimately a music first person irrelevant presentation, but modern black metal is a wide spectrum, it has some of the most image conscious crap out there too, if anything I think its probably the most superficial and image focused of the main metal genres. It's just that anonymity hasn't historically been part of death metal culture that much but I feel its actual presentation is quite workman like in many ways.
