An unlikely but exciting pairing, Alison Krauss and Robert Plant recently finished a collaborative album, 'Raising Sand', to be released on 29th October. The songs range from modern to classic, consisting mostly of lesser-known material from a wide spectrum of great blues, R&B, country, and folk songwriters - Tom Waits, Gene Clark, Little Milton Campbell, Mel Tillis, Townes Van Zandt, Doc Watson, Phil and Don Everly.
