The singer Robert Plant said was sent from heavenThe legacy of Led Zeppelin was never that big of a concern for Robert Plant. He wanted the chance to spread out, and sometimes the greatest collaborators have a divine charm to them before they even sit down to write music. But whatever Plant was going to be doing after Zeppelin, it was going to have to go in a different direction. Unledded was a great idea that happened to become larger than life, but if people enjoyed the more lowkey take on classic Zeppelin tunes, maybe they would go for a version of Plant that was more downbeat. It may have involved years of him fumbling around in the dark to get the right sound, but like all good Zeppelin tunes, albums like Raising Sand always come back to the quality of the music rather than some bold leap forward.
