Classical at the Freight brings the Bay Area's best classical musicians to our stage for an hour of top-flight chamber music in an informal, friendly atmosphere. San Francisco Chamber Orchestra music director Benjamin Simon is your host; his goal is to un-stuffify and de-mystify classical music for the general music lover, sharing the joys and rewards of this timeless art with new audiences young and old.

Join Benjamin and the Sor Ensemble tonight to celebrate Beethoven's birthday! Wei He and Karen Shinozaki (violins), Emily Onderdonk and Rem Djemilev (violas), and Eugene Sor (cello) are consummate chamber musicians, friends, colleagues, and co-stars of the recent documentary "Freeway Philharmonic." Tonight they perform pieces celebrating the master's 238th birthday, including his seldom-performed but wonderful Viola Quintet.
