Into the Pandemonium is the second studio album by Swiss extreme metal band Celtic Frost, released in 1987. The album is more varied than Celtic Frost's past LPs, with unlikely covers (Wall of Voodoo's "Mexican Radio"), emotionally charged love songs, the album's recurring industrial-influenced rhythmic songs of demons and destruction, traditional Frost-styled songs about dreams and fear, and a dark, classical piece with female vocals.
The album is vastly different from the band's previous work which cemented its late 1980s avant-garde metal term; it is also a departure from the style found on the band's previous albums, Morbid Tales and To Mega Therion that Celtic Frost had become known for. However, it does have the recurring symphonic elements found on previous albums. The album has a more classic heavy metal style within the songs with elements of industrial, classical, gothic rock and doom metal. Eduardo Rivadavia of AllMusic called it "one of the classic extreme metal albums of all time."
