There is more than one artist with this name:

(1) The Hip-Hop formation Nuclear Family started in 2001 after the groups "3e Kamer" (MC's Ki & Vecsy.D and producer B-ski) and "Pickpockets" (MC Ahab and producer Tommy2Times) merged to release their first album in 2002; "3e Kamer & Pickpockets Present Nuclear Family". Which was meant to be a one-time project for the two Hip-Hop groups grew out to be a smashing debut album of the Nuclear Family.
The formation from The Hague got famous for their mixture of the Dutch and English language, but also got criticized by labels and radio stations for the same reason.

After internal struggle the formation was forced to change line-up and made their fans wait for over 2,5 years to release the follow-up album in 2005; "Nuclear Fission/Kernsplitsing". The new line-up consisted of 5 members; the brothers Ki and Ahab, Vecsy.D, Tommy2Times and new member Mic-Nif. Again the formation chose for a Dutch / English mixture.

In 2007 the Hip-Hop formation called it quits. Ki, Ahab and Tommy2Times made a restart under the name "Kern Koppen" (Nuclear Heads) and chose to use the Dutch language only.

(2) UK-based band Nuclear Family formed in 2006 and released an EP (entitled "volume one") in 2007.

(3) Berlin/Copenhagen-based electro punk pop duo Nuclear Family formed in 2005 as part of the Copenhagen queer art collective dunst.

Members Nikolaj Tange Lange and Andreas Tange Lange started their career together by marrying at the townhall in Copenhagen. Since then they have played shows all across Europe. Usually splashing around in ketchup or stage blood, starting in pecualiar costumes ending up half naked.

Nuclear Family have songs released by Copenhagen label Broken Mirror Records and Scream Club's label Crunks Not Dead. Debut album comming in 2008.
