Voices and Visions was a 13-part educational t.v. series (13 t.v. programs), produced in 1988 by the New York Center For Visual History and airing that year on public television. The programs attempted to explore, as they put it, “through interviews, archival footage, and readings, the life and works of some of America’s greatest poets”…”Each of the thirteen 60-minute documentaries focuses on a different American poet and attempts to present a biographical picture of the poets’ life and insight into the poetry they created”.
The clip begins with James Laughlin of New Directions,Williams’ friend and publisher, recalling Williams. This is followed by (audio only) Allen, sensitively reading from Williams’ classic 1923 volume Spring and All (recently re-published, by New Directions, in an elegant facsimile edition).
