2/1 through 2/10 — Theater: Proof of Life Jeffery Michael Janes lost his sense of identity as he fell from extreme privilege to solitary homelessness in San Francisco. His dedication to documenting his descent into namelessness was his path out of madness, and the engine behind Proof of Life, opening at the Potrero Stage February 1. The brainchild of drama therapist Lena Mullins, the play is a textured blend of Janes’ writing, the creative license of playwright Richard Ciccarone, soulful cello, and operatic voice. “The choices he made were quite extreme, but the story is that universal theme of questioning your existence, the drive for survival and what one will do to prove you are a part of this world and what you go through to cling on,” said Mullins. Janes’ compelling story led Mullins and Ciccarone to create Passing Words, a theater company founded to produce works that give witness to an individual’s life. Proof of Life is their first production. Starring Lena Mullins, David Richardson, Chris Pflueger, Cole Alexander Smith, soprano Ann Elizabeth Jones and cellist Eugenio Solinas. 8 p.m., February 1, 2, 3, 8, 9, 10. The Potrero Stage, 1695 18th Street. For more information: www.passingwords.com.
