Festival of Underground Poetry :

Beat poet Diane di Prima reads excerpts from her book "The Calculus of Variation" at the Festival of Underground Poetry at the UC Berkeley Art Museum on October 10, 1971. The festival was co-sponsored by the UC Berkeley Art Museum and the Berkeley Poets' Commune. Recording starts in the middle of a sentence and seems to be excerpted from a longer reading. The recordings cataloged as BB5296 [1] and BC0628 [2] also contain audio from this event. [1] http://pacificaradioarchives.org/recording/bb5296--[2] http://pacificaradioarchives.org/recording/bc0628.
