José Nieves (R.K.M) and Kenny Vázquez (Ken-Y), both of Gurabo, Puerto Rico, are a Grammy Award-nominated reggaeton duo.
The duo started their career of music in high school. R.K.M (formerly known as "Rakim" but changed to avoid confusion with established Hip-Hop artist Rakim) was inspired by the recent explosion of reggaeton music in the 90's. He encouraged Ken-Y to join him to form a duo. They later would perform at sweet 16 birthday parties and public events.
