Into the Pandemonium is the 1987 album by black/thrash metal band Celtic Frost. The album is more varied than many of Celtic Frost's past LPs, with unlikely covers (Wall of Voodoo's "Mexican Radio"), emotionally charged love songs and the band's signature industrial-influenced rhythmic songs of demons and destruction. The track "Rex Irae" is the opening part of Celtic Frost's requiem, the third, concluding part of which, "Winter (Requiem, Chapter Three: Finale)" can be heard on 2006's Monotheist. The second part of the requiem was never released by the band. Some of the lyrics are silently borrowed from other sources. For example, significant portions of Inner Sanctum are directly quoted from Emily Brontë poems. The cover image is a detail from the right (Hell) panel of The Garden of Earthly Delights, a triptych painted in 1504 by Hieronymus Bosch, now part of the permanent collection at the Prado in Madrid.
