I think there's a point of diminishing returns on listing every band, on a poster for a big festival with a bazillion bands.
If I were the promoter, and I'm not, but if I were, I would have asked for the poster to list just the marquee acts. If this is the alternative.
I'm quite certain that this was NOT the designer's call, and that they were doing what they were asked to do.
But yeah...cereal box, with the ingredients on the front. Slight prominence to headliners Wheat Flour, Corn Syrup, and Vegetable Oil.
I'm really not sold on the Sword being the Real Deal. At all.
Not that I mind, or am in any position to judge, as I play in a fake-ass metal band too, and make no claims otherwise.
But based on having seen them twice and having heard their records...
My impression is that the Sword are absolutely an indie-rockers-playing-metal metal band. With irony aplenty.
