Ceremony of Opposites is the third album by Swiss extreme metal band Samael. This is their second release with Century Media Records after leaving French label Osmose Productions. Although the band's subject matter was similar to previous releases (references to Aleister Crowley, Satanism and blasphemy), it also showed their first signs of interest in industrial music, a direction that they would take on future albums. It was produced by Waldemar Sorychta, who also worked on recordings by Lacuna Coil, Tiamat, Moonspell and others. In 2005, the album was re-issued with their 1995 Rebellion EP.
