Glenn Gould: A Portrait is a biography of pianist and "explorer of sounds" Glenn Gould. The 105-minute program -- a montage of interviews, photographs, recording sessions, and concerts -- depicts the life and times of this late musician. Highlights of the film include pictures and scenes from Gould's life in Canada, as well as interviews with Geoffrey Payzant, broadcaster Margaret Pacsu, musician John Peter Lee Roberts, and music critic Paul Hume. Gould's personal views on animals (especially his affinity for skunks), his psychiatry, pacifism, and solitude are reflected on by family and friends.
