The Matrix
3138 Fillmore Street, Cow Hollow, San Francisco
Jefferson Airplane played the opening night, 13 August 1965.
Balin had met Paul Kantner at another club, the Drinking Gourd, and found Signe Anderson there through her brother, who tended the bar.
The Matrix closed early in 2018, and the room became a bar called White Rabbit.
Now a bar. See the front on Fillmore Street, between Greenwich and Pixley.
