You've probably heard that famous chestnut, "Writing about music is like dancing about architecture." Well, experimental dance company Post:Ballet, now finishing up a residency at the Yerba Buena Center for the Arts tonight, has covered the dancing about architecture part, with a collaboration between choreographer/company artistic director Robert Dekkers and Bay Area architect Robert Gilson called field the present shifts. It's one of four of the Four Plays the company is performing, tonight is the last performance, and there are still a few seats available.

The new piece "focuses on the space between objects, making observations on the relationship between individual and community, freedom and constraint, finite and infinite," and involves a structure in which the dancers are allowed to improvise and make choices in each performance that affect the direction of the performance.

And there's an added cross-medium work too: Jeffrey Zygmunt has done 20 castings of Post:Ballet dancers inspired by field the present shifts, which are on display in the lobby.
