Bottled Songs 1-4 is a series of video letters exchanged between Chloé Galibert-Laîné and Kevin B. Lee, documenting their investigations into online media related to the audiovisual propaganda produced by the terrorist organization Islamic State. These “desktop epistolaries,” recorded on the artists-researchers’ computers, portray their experiences navigating an unstable virtual environment of fear and attraction. These investigations combine to provide a multifaceted account of the images, people, and networks that constitute an unruly sphere of online terrorist media. Selected for the 2021 Rotterdam Film Festival.
