A member of the hitmaking Monsters & Strangerz songwriting and production team, Oliver “German” Peterhof has a production style that is crisp and bold yet always soft along the edges. He can bring out an artist’s most vulnerable side, as heard on emotional cuts like Justin Bieber’s soulful ode to his wife, “As I Am"; Katy Perry’s electro-pop empowerment anthem, “Electric"; and Julia Michaels’ romantic confessional “Little Did I Know.”
