That's the song Adam Lambert chose to sing on "American Idol" rock night Tuesday (May 5), and, needless to say, it was a challenge that the eyeliner-loving Los Angeles stage veteran was more than up for, hitting a series of high notes and rock screams that would have made Plant proud. It was a risky maneuver that paid off for Lambert, who chose a tune that came in at #75 on Rolling Stone magazine's list of the "500 Greatest Songs of All Time" in 2004.
The performance was impressive, but a bit too "metal" and maybe even "feminine" for a true Zeppelin cover. Nice try though.
