Many members of different bands have been part of Tartaros.

Joachim "Jay Arr" Rygg was writing and producing music for some of Europe's hottest TV shows, including Norway's popular "Big Brother" series. The show's theme song, composed by Jay Arr, was released as a single and became the most-played song at radio that year. Jay Arr was writing and producing for several artists, and a chance encounter with one of Chobo's sisters put the two in touch. After creating a few magical songs together, they laid the foundation for what was to become the Dual Nations Collective: The DNC.

Jay Arr and Chobo envisioned The DNC as "urban/pop mixed with hip-hop at a non-stop party." They wanted to incorporate an international sound in contemporary party music with the fun and swagger of legends like James Brown, Ray Charles, Michael Jackson, Tom Jones and Salt 'N Pepa.

Seeking new opportunities for The DNC, Jay Arr packed up his gear and came to the United States. Since then, The DNC's music has been heard by millions of ears in movies and television shows, including "Center Stage 2", "Ping Pong Playa", "Save The Last Dance 2" , "American Pie: The Naked Mile", "How I Met Your Mother"," "Las Vegas", "CSI: NY", "Dollhouse", "Ghost Whisperer", "Scrubs," . The DNC's "Swing Baby Swing" is being used in a national television advertising campaign in Canada commemorating the 25th anniversary of their Lotto 649 game.
