As the name implies, Toychestra plays toys. The six Oakland-based women in the ensemble use actual instruments, like toddler-sized pianos, xylophones and drums, and a wide range of toys, such as a pink Zoo Train, that just make great sound. They also use a washboard, pots and pans, and a jack-in-the-box for percussion. Toychestra’s sweet, well-orchestrated cacophonies can be heard on Saturday, December 6. From 1-2:30pm, they will lead a participatory workshop for families, and then, at 3pm, Toychestra performs in the Exploratorium's McBean Theater. Toychestra is presented in conjunction with Toying Around, a series of toy-related, special holiday events at the Exploratorium during the month of December. For workshop registration and performance reservations, please call (415) 674-2870. Both events are free with admission to the Exploratorium.
