The American Cinematheque brings one of the Northwest’s top independent filmmakers, Gregg Lachow, to Hollywood for screenings of four of his films, including the latest, “Silence!” Lachow, a graduate of Harvard and a former editor of the Harvard Lampoon, has been making films since 1987, originally working with Super-8 and incorporating the work of the interdisciplinary performance group Run/Remain. His first stand-alone piece was 1992’s “To Have and to Hold” for PBS, which was nominated for an Emmy. Lachow has made four features in the last eight years, culminating with “Silence!,” a unique silent film that incorporates live performance of dialogue, music and sound accompaniment by seven actors and six jazz musicians.

8 pm / Jazz

Keiko Matsui is Billboard’s No. 1 female contemporary jazz artist, with only Kenny G and Boney James ahead of her in the smooth instrumental music field. Matsui’s real charm, however, lies in her capacity to place gently evocative melodies over irresistibly groove-oriented rhythms. Look for the slender Japanese artist to go dramatically against type by hanging a portable keyboard over her shoulder and stepping to the front of the stage in pure rock-star fashion.

* Keiko Matsui, Cerritos Center for the Performing Arts, 12700 Center Court Drive, Cerritos. 8 p.m. $32-$43. (800) 300-4345.
