HAMMER! is the first book by influential filmmaker Barbara Hammer, whose life and work have inspired a generation of queer, feminist, and avant-garde artists and filmmakers. The wild days of non-monogamy in the 1970s, the development of a queer aesthetic in the 1980s, the fight for visibility during the culture wars of the 1990s, and her search for meaning as she contemplates mortality in the 2000s-HAMMER! includes texts from these periods, new writings, and fully contextualized film stills to create a memoir as innovative and disarming as her work has always been.

HAMMER! was the winner for the 2010 Judy Grahn Award for Lesbian Nonfiction.
