Directed by German filmmaker Rüdiger Nüchtern, this behind-the-scenes rock documentary captures Amon Düül II, as the progressive rockers record their debut album, "Phallus Dei," in a Munich recording studio in 1968. Blending performance footage with a collection of psychedelic nature clips, Nüchtern's meditative film captures the true essence of the legendary krautrock collective. The movie premiered at the Edinburgh Film Festival.
