The band consists of Juho "Jun-His" Vanhanen (vocals, guitar), Korjak (drums), Moit (guitar), Evil (keyboards, percussion) and Ontto (bass guitar). The band takes its name from "oranssi", the Finnish word for "orange" and Pazuzu, a wind demon from Babylonian mythology.

Their second full-length album, Kosmonument, was released in 2011 through Spinefarm. In 2013, Svart issued the follow-up, Valonielu which was produced and engineered by London-based producer Jaime Gomez Arellano. The band''s album Värähtelijä was released in 2016 and received positive reviews from music outlets such as AllMusic, Pitchfork and Spin. In 2017, the band released the two-track EP Kevät / Värimyrsky.

AllMusic''s James Christopher Monger described the band''s music as a combination of black metal, psychedelic rock, space rock, and progressive metal.
