Pandemonium is the second greatest hits compilation album from Taiwaneseblack metal band Chthonic. It features eleven tracks from eleven years of band history (1996 – 2007). It follows A Decade on the Throne, a live album and DVD intended for the Asian market.
A Decade on the Throne and Pandemonium are identical with regards to the track listings, up to a total of nine songs. For Pandemonium, however, seven tracks were re-recorded with the band's main drummer Dani, who, after an injury during a live show in 2005, was replaced by Reno Killerich for the recording of Seediq Bale. At the time of the release of Pandemonium, the band toured Europe and the U.S., spreading their message of an independent Taiwan that wants to contribute to international society regardless of Chinese oppression.
