There are five bands known as Zyklon-B.
A. Black Metal Project from Norway with members of Emperor, Satyricon and Dødheimsgard.

Very fast, aggressive and atmospheric tracks about war, violence and depopulation of the earth.
Members: Samoth: Guitars (confusingly, also a member of the completely unrelated band, Zyklon); Frost: Drums; Draug Aldrahn: Vocals; Ihsahn: Keyboards.
