Under the helm of producer Oscar de Leon, established reggaeton duo Jowell & Randy joined forces with fellow Puerto Ricans Guelo Star, Maximan, and J-King to form the group Casa de Leones. Their debut single, "No Te Veo," was an immediate hit, setting the stage for Casa de Leones (2007), the group's debut album for Warner Music Latina. ~ Jason Birchmeier, Rovi
