Don't doubt it for a moment: Robert Plant's legendary vocal cords are intact and functional. More than that - they soar, plead, wail, whine and declare as well as they did decades ago when he was rock 'n' roll's No. 1 rebel. It's the music that's changed, not the voice.

The world should continue to thank T-Bone Burnett for putting Robert Plant and Alison Krauss together in 2007 for "Raising Sand," an album of pure musical magic.

On "Band of Joy," his 2010 release, Plant and the band recapture some of that magic in shuffling percussion, longing harmonies and empty-room reverb. The sound is bluesy, the songs filled with stories.
