Sleepbomb is a San Francisco-based cinematic psychedelic post-rock band focused on full, original scores for genre films including the German Expressionist silent masterpieces - The Cabinet of Dr. Caligari, Nosferatu and Metropolis, George Romero’s 1968 classic zombie film Night of the Living Dead and the epic swords & snakes of John Milius’ 1982 Conan the Barbarian. Historically a live experience, Sleepbomb has performed their scores across the West coast of the US since 2003 and now has set their sights on expanding across the US and beyond.

Musically, Sleepbomb ranges from heavy doom riffs to dreamy shoegaze, dark soundscapes punctuated with shimmering guitar and ethereal vocals. Originally stylistically close to a chaotic version of Throbbing Gristle vs Black Sabbath, Sleepbomb has been exploring experimental sounds and forms, guided by the band’s love of Godspeed You! Black Emperor, Coil, Neurosis, Sunn 0))), Ulver and Swans, among others. Settling on a drone influenced style of psychedelic post-rock as the overarching theme while exploring other genres as appropriate for each film’s particular style, Sleepbomb’s goal is to re-contextualize the experience of these well known films. They succeed in this goal.

Sleepbomb joined Bill Gould’s koolarrow records and Belgium’s Consouling Sounds in 2023 for the release of their score for the classic 1920 German Expressionist film The Cabinet of Dr. Caligari. They were overjoyed to repeat this collaboration for their 2025 release of The Sleeping Dead: excerpts from an alternate score for George Romero’s Night of the Living Dead. Up next - Conan the Barbarian.
