A trailer for Jack White's forthcoming three-part music documentary 'American Epic' was recently aired, and promised to document ""the music and musicians recorded by talent scouts for major record companies in the 1920s", as well as feature numerous contemporary musicians recording with equipment from the 1920s.

One of the featured artists was rapper Nas, and now footage of him performing his song 'One Mic', taken from his 2001 album 'Stillmatic', with White backing him on piano has been revealed.

With two other musicians on double bass and percussion, it makes for a pretty special performance.
