This record describes the main focus of Berliners Gernot Bronsert and Sebastian Szary: hang out together all the time. Both dudes will become fathers very soon, almost simultaneously -- happy birthday! But back to their labor-pains: After 111 slashings and burnings across dancefloors from Sydney to Iceland, and driven by the ungovernable spirit of gold-diggers, Gernot and Szary holed up in their mobile Airstream caravan recording studio in order to give birth to Happy Birthday!. The conditions of production were slightly adverse, but thanks to digital transfer technology and a mild winter in Berlin, it all came together nicely in the end.

The repertoire of Happy Birthday! runs from hard rap with a French kick to dubstep in the broadest sense. New urban word scraps attempt to describe Modeselektor's style: Eurocrunk, continental grime, tech-rap... the list is long. Mr. Bronsert and Mr. Szary don't like to put a genre sticker on their music anyway, so they don't really care. They just do great music, no matter what style.
