Pinea Silva: Lost Meanings of the Christmas Tree, a performance-lecture by Carolee Schneemann, was first presented on December 15, 2011 as part of the 40th Anniversary Benefit at Electronic Arts Intermix (EAI). The live recording, which was edited by Schneemann at EAI, represents an audio-visual collage in which the images used in the artist's lecture intervene in the recording of the lecture itself.
