After the storm and fury of Led Zeppelin, Robert Plant’s debut solo album is light and clean, with sharp New Wave guitars (“Fat Lip”) and angular Police-style rhythms (“Pledge Pin”) largely replacing the bludgeoning riffola of yore, “Mystery Title” aside. His voice retains its pleading edge, sobbing against the flamenco guitar of “Moonlight In Samosa” and bolshy and confident against the funky blues of “Worse Than Detroit.” And in the opening seconds of “Slow Dancer,” there’s still room for the odd blood-curdling scream.
