Sideshow Symphonies is the fourth studio album by the Norwegian avant-garde metal band Arcturus. It was released on 19 September 2005. It is the first to feature Simen "ICS Vortex" Hestnæs as the principal vocalist and Tore Moren as second guitarist, as well as the first Arcturus album released by Season of Mist.[1] It marks yet another change in Arcturus' sound, with a cold, dreamy aesthetic featuring relatively quiet guitars, more prominent vocals, and a slightly reduced use of synthesizers.

La Masquerade Infernale (Misspelled French for The Infernal Masquerade. The correct spelling would be La Mascarade Infernale.) is the second studio album by Arcturus. Released by Misanthropy Records in 1997, the album marks a drastic musical change from the slow, nature-influenced melodic black metal of Aspera Hiems Symfonia. Most of the songs revolve around the themes of theaterliterature, and Satan. The screams characteristic of black metal utilized by Kristoffer Rygg on Aspera are replaced by a gruff, low-toned, clean vocal style.[4] 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.
