"A Mixtape for Stom" is an intimate documentary portrait of Japanese experimental filmmaker Stom Sogo (1975–2012), whose frenetic Super-8mm works became emblematic of New York’s underground cinema at the turn of the millennium. A close friend, filmmaker Adrian Goycoolea reflects on Sogo’s life and legacy, framing the film as a reply to the final email he received from him. Drawing from personal archives, interviews, and memory, the film assembles a collage of Sogo’s art and presence: radiant, restless, and unresolved. Contributors include Jonas Mekas, Bruce McClure, Raha Raissnia, Julius Ziz, Ed Halter, Andy Lampert, and members of Sogo’s family, offering perspectives on his talent, struggles, and influence. Scored by Joe Watson of Stereolab, "A Mixtape for Stom" is at once an elegy and an act of remembrance; a meditation on friendship and grief, and a testament to an underground legacy that continues to reverberate.
