Arguably one of the most talented and respected artists of his generation, Kenneth Rexroth was not only a venerated poet, but an essayist, literary critic, translator and painter. Perhaps most significantly, Rexroth was considered the instigator of The San Francisco Renaissance. “The Signature of All Things” serves as an ode to the artist, documenting a night of tribute on his 100th birthday. Held at Beyond Baroque, the notoriously avant-garde Literary Arts Center in Venice Beach, this celebration attracted an eclectic roster of participants extolling Rexroth’s impact on an art form. This film memorializes Rexroth with wild recitations and wry reminiscences from the assorted friends, family members, former students, writers, music archivists, performers and poets who knew him best. This documentary expresses, in its unassuming artistry, a lasting impression of an American original.
