Robert Plant is getting recognized outside the rock arena.  The former Led Zeppelin frontman is one of the top nominees heading into the Americana Music Association Awards.

He's a contender in three categories, including Artist of the Year.  In addition, he and his group Band of Joy are in the running for Duo/Group of the Year, and the CD "Band of Joy" is among the discs vying for Album of the Year.  Plant's primary competition is Elizabeth Cook, who's also a three-time nominee and also up for Album and Artist of the Year. The 2011 Americana Music Association Honors and Awards will be presented in a ceremony at Nashville's Ryman Auditorium tonight.
