The title of the film conveys the dual meaning of the word—as both an accounting and a reverberant or explosive signal, echo or announcement of an event—and the film carries its full freight. The actual fragments of live radio broadcast transmissions that comprise the soundtrack are an accompaniment as much as reportage in the conventional sense.

It is difficult to categorize the boundary-breaking, multi-media trajectory of American artist Bruce Conner (1933 – 2008). Constant change and a wide-roving, obsessive curiosity are perhaps two constants in Conner’s work, which ranges from assemblage to drawing, painting and sculpture to conceptual art and experimental film.

The museum dove into its huge collection of art created since World War II and emerged with Crossroads: Carnegie Museum of Art’s Collection, 1945 to Now. The museum’s re-installed contemporary galleries will include about 150 paintings, sculptures, photographs, installations, and films, organized not chronologically, but under eight themes (or “chapters”). And the focus is on works that are either new to the museum or have not been shown in decades.
