The appeal of Robert Plant’s Lullaby and the Ceaseless Roar is that it sounds far older than it is. It sounds like something Plant himself might have done in the 60’s if his approach to making music had been less bombastic. It may have taken him decades to realize that everything doesn’t have to be screamed, but his roots haven’t changed. He still likes blues and folk music. And that’s just fine. No one wants to see Robert Plant get modern. I mean, no one wants to see old geezers trying to be edgy in general, which leaves old geezers with very few options. They could try to be edgy and embarrass themselves, or continue producing new material that sounds exactly like their old material, or stop producing new material altogether and just play the hits. Robert Plant is of the few who refuses to play the goddamn hits, and he’s also one of the few who still writes material that is both reminiscent of the old stuff and different enough from it to be interesting.
