Raising Sand is a Grammy-award winning collaboration album by Led Zepplin vocalist Robert Plant and bluegrass–country singer Alison Krauss. It was released on October 23, 2007 by Rounder Records. Raising Sand won Album of the Year at the 2008 Americana Music Honors & Awards and at the 2009 Grammy Awards. Their harmonies are beautiful. My favorite cuts off this 13 track album are Rich Woman, Please Read The Letter, Fortune Teller, and Killing The Blues. This album was very well written, performed and recorded. I highly recommend this album to anyone’s music library.
