[1][2] Erik og Kriss began their musical career when they created the russ song Legenden in 2002 for their own russebus of the same name and made it available on the bus's ad hoc website.

The duo went into business with the ArtistPartner agency in the start of 2006, who would take over all the paper work, and set up the group's concert and travel plans.

Both in the song Oppblåst På Livstid, and in Putt Diamanter Opp, which is a cover of Lil' Kims Lighters Up, they shape an exaggerated and almost pompous portrait of Bærum and their own adolescence.

In recent times, after the group reached an agreement with MTG Music, the lyrics of Erik og Kriss have been characterized as having a more serious undertone.

The music of Erik og Kriss has an amusing tone – a style they have kept since the start – and attempt to spread the good message through their songs.

The media personality Tor Milde contributes in the song Anmeldelsen from Gull og Grønne Skoger produced by football player Christer George.

On Verden Vil Bedras, the country singer Finn Wang, rock vocalist Martin Diesen from Inglow, and the world-renowned American rapper Coolio contribute.

In the Fall of 2008, Erik og Kriss will take part in TVNorges biggest production ever, with the TV program Grease along with Henriette Lien.
