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, her search for meaning as she contemplates mortality in the past ten years-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.
