Whoa! I'm so excited! It's not everyday the marketing for a "Grammy-winning, Platinum-selling [sic]" band specifically targets me and my punctuation pedants demographic.
For there is no way this will appeal to anybody but us steely-eyed grammar nerds:
Looks like we got ourselves one of those *intellectual* bands - showing the mettle of their metal to become a geek crossover hit. After all, they did name one of their songs "Wherein Lies Continue" - I'm not sure if that's grammatically sound, or what it means, but it sure does sound brainy.
As for the poster, they must of been inspired by this t-shirt. And the DVD they're selling must tell the moving story of how the Loch Ness monster swims to France, frenchifies his name, and produces a whole brood of .... Nesses.
