During the last 15 years of his life, famed American composer John Cage (19121992) created an extensive body of hand-drawn scores, maps and prints. Crown Point Press, kicking off its 50th anniversary, presents a selection of these works made at Crown Point in the late '80s.

Through drawings, sculpture, video, photographs and large-scale cut paper, Colburn mines her travels with scientists to remote destinations to study climate change. Trips to Antarctica, the Amazon, the Andes, along with a recent voyage between Barbados and French Guyana, inform the work.

Amanda Kirkhuff's extraordinary portraits of ordinary women--sometimes beset by extraordinary circumstances--is complemented in this exhibition by a limited-edition broadside by Amy Scholder, editorial director of the Feminist Press imprint at City University in New York.

This group exhibition presents work by first-year MFAs at Stanford. Works include 16mm film, video, painting, installation and collaborative performance. Of particular interest: Work derived from Greg Stimac's "virtual travels" and Dawn Weleski's residency in Cairo last year.

Sigfried Giedion's "Space, Time and Architecture" is a conceptual springboard for this two-person exhibition exploring space--the built environment and the cosmos--as a physical entity, both boundless and confined. Its setting in an "alternative space" further illuminates these parallels.

Ancalmo, a current awardee featured in SFMOMA's SECA exhibition across the road from the gallery, mines outmoded technology, such as 16-mm film projectors and word processors, to create visually compelling images and installations that plumb our sentimental attachments.

From the press release: "HUE extends the premise of audience participation articulated by Marcel Duchamp in The Creative Act (1947); that the viewer completes a work of art. When we see a shift in hue, either by walking past or through digital means, the work of art is complete."

Contemporary artist Hiroshi Sugimoto creates a post-humous collaboration with 19th-century inventor William Henry Fox Talbot by printing from original negatives from Talbot's early photography experiments. The resulting landscapes present luminous and compelling netherworlds.

This group exhibition, curated by Aimee Le Duc, features work by Heather Sparks and Gail Wight, among others. The unifying theme explores space that is "either so large or so small we cannot conceive of it with our known processes"; featuring photography, video and installation.
