Program Three: VOICE

Our voices are as distinctive as our faces.

Peter Nicks’s film “Stutter Step” profiles the great college running back Adrian Peterson, whose stutter can make his speech as halting as his feet are swift.

The 19th-century show-business phenomenon “Blind Tom,” an illiterate slave, wrote and performed lush romantic piano music; John Davis plays Blind Tom’s compositions in this sequence from producer Jill Rosenbaum.

Host Michel Martin interviews ventriloquist Spencer Horsman, and filmmaker Alix Lambert contributes a portrait of her “Uncle Stanley,” 95 year-old poet Stanley Kunitz.
