The show's full name is
The B-Side: Negro Folklore From Texas State Prisons: A Record Album Interpretation, and it's
an original performance based on
an LP of work songs, spirituals, and toasts recorded in 1964 in
Texas’ then-segregated prison farms. Presented by
Eric Berryman,
Jasper McGruder, and
Philip Moore of NYC's nigh-on legendary
Wooster Group, the production also provides context from the book
Wake Up Dead Man: Hard Labor and Southern Blues by
Bruce Jackson, the folklorist who recorded the album.
