'Heart Beat Ear Drum' is a feature length documentary about the late artist and musician Z'EV (1951-2017), known for his punk era scrap metal music - an extraordinary range of acoustic phenomena resulting in trance-inducing sounds. This documentary shows how his music changed and grew and how his personal journey led him to the margins of art and the depths of heart. From 2007-2015, director Ellen Zweig followed Z'EV, shooting concerts and interviews, and collecting archival footage. In addition to interviews with Z'EV, there are interviews with a community of artists who have known him since the 1970s, curators who have encountered him in the 1990s, and younger people who have only heard his recorded music or read his philosophical texts (Bob Bellerue, Bow Gamelan Ensemble, HATI, Barbara Stevini, Simone Forti, Zach Layton, Carl Stone, Ned Sublette, Johanna Went and more).
