Miami-based production duo Marcello “Cool” Valenzano and Andre “Dre” Christopher Lyon made a name for themselves producing for Fat Joe, but would soon catch the attention of hip-hop heavyweights like The Game—producing his hit 50 Cent collab "Hate It or Love It"—Ja Rule, and Wale. They continue to work primarily in hip-hop, but they've also worked with R&B stars like Kelis and Christina Milian.
