La Masquerade Infernale

La Masquerade Infernale is the second studio album by Norwegian avant-garde metal band Arcturus. Released by Misanthropy Records in 1997, the album marks a change from the slow, nature-influenced symphonic black metal of their debut Aspera Hiems Symfonia. Most of the songs revolve around the themes of theatre, literature, and Satan. The screams characteristic of black metal utilized by Kristoffer Rygg on Aspera are replaced by a gruff, low-toned, clean vocal style. The album also features operatic singing and bizarre high-pitched singing from guest vocalist Simen Hestnæs, who nine years later would replace Rygg as the band's frontman. It was reissued by Candlelight Records in 2003.

In 2021, it was elected by Metal Hammer as the 12th-best symphonic metal album of all time.
