A gun, a bottle of Jack Daniels, a splatter, a million beads. With these details, the California artist Liza Lou tells you stories. And just a minuscule bead, she explains, is like an underlined word: it can focus your attention, and slow you down.

“Beads highlight what is ordinary and make you look at it,” said Lou, known for her life-size beaded sculptural installations, including “Kitchen” (1991-96), in the collection of the Whitney Museum, and “Back Yard,” acquired in 2002 by the Fondation Cartier. She was speaking recently in front of “Trailer,” another massive construction, originally made 25 years ago and filled with tens of millions of Czech glass beads. It just arrived at the Brooklyn Museum.

Lou, 55, has reached a turning point in her career, as she transitions from the objects that put her on the map — the Museum of Modern Art recently acquired a beaded teacup and saucer — into more abstract work, all created with her favorite material, which she called “tiny messengers of pigment, dot size expressions of joy.”

Carmen Hermo, a curator who worked on the “Trailer” installation, said, “There is a tenderness to the attention that Liza pays” to every detail and bead placement. The meticulousness of works like “Trailer,” she added, “just kind of messes with your mind. There’s something so everyday but also very uncanny about it.”
