It’s true, it might seem odd at first, having a German-speaking rock band and an American motorcycle company join up to produce a music album. However, Frei.Wild have won numerous gold and platinum awards, and various of their albums made it to the top of the charts, consecutively, which makes them one of the most successful German rock bands. And OCC are known to the worldwide public due to their extravagant motorcycles and their very own TV show, “American Chopper”, watched by millions of people. However, it is less known that both have been sharing a deep friendship for years, also sharing continents, as well as events and trips. This friendship, combined with shared memories of fun times in the United States and southern Europe is what resulted in a joint project named “Brueder4Brothers” and its debut album Brotherhood.
