The event will mark both the first trip to the awards and first performance for Robert Plant, who says: "I'm looking forward to being in Los Angeles, but musically -- and spiritually -- I expect we'll be somewhere halfway between the Mississippi Delta and the Clinch Mountains."

Robert Plant and Alison Krauss have been honored with nominations in five categories for 'Raising Sand' (Rounder Records). In addition to 'Album Of the Year' and 'Record Of the Year' (for "Please Read The Letter"), 'Raising Sand' garnered nominations for Best Contemporary Americana/Folk Album, Best Pop Collaboration With Vocals (for "Rich Woman"), and Best Country Collaboration With Vocals (for "Killing The Blues"). The nominations add to last year's win for Best Pop Collaboration with Vocals for "Gone Gone Gone."
