I'm a bit confused with the Darkness references - they were a cheesy 80s parody band for the pop market place? I don't see the relationship to the other band you mention. It's not like people took them seriously at any stage.
Yeah, they were garbage. I hate when a band like that comes out and people are like, "Yay, rock and roll is back!" Whenever a band has come along and REALLY rejuvenated rock, it's because they were innovative, not completely derivative of something that's already been done.
