Led Zeppelin?s Robert Plant and Jimmy Page are back in creative cahoots, with their first new original material in almost 20 years. The stylistic loop continues, from the weirdly catchy strains of the first single, ?Most High,? to the post-?60s pop charm of ?Please Read the Letter.? Plant?s Moroccan-blues swagger and Page?s unmistakable, scruffy-smart guitar touch come together beautifully. This song set sounds both vintage and, thanks to the lingering Zep craze, of the moment.
