The song, 'Wayfaring Stranger,'is most famously recorded by Burl Ives but also covered by literally hundreds of artists.  The collaboration is featured on 'Re:Generation,' a documentary that features five DJs working in unfamiliar genres, such as R&B, jazz and classical. The film, directed by Amir Bar-Lev ('The Tillman Story') is due out in early 2012, and will also include Erykah Badu, members of the Doors, Mark Ronson, Mos Def, Martha Reeves, the Crystal Method and Skrillex.
