Sirius has been active in the hip hop community since 2002 and has several albums and mixtape releases behind. It was in 2010 he got the breakthrough with the song "Fuck up" (4xplatina).

Since then he has been involved in both VG tour, Vinterlyd and played individual concerts in many parts of Norway.

In 2012, Sirius took a break from the spotlight to work on developing himself as a songwriter and composer. In the studio he was working closely with producer Simen Fjeld and got back into a sound and way of writing texts that make Sirius unique in the genre in Norway. He is perhaps best known for the more personal songs like. "Thank you" and "Always on my mind" both of which have well over 200,000 hits on youtube and the latter has also been certified gold.
