Jose Nieves (Rakim) and Kenny Vasquez (Ken-Y) joined forces in 2004 to form the reggaeton duo Rakim & Ken-Y. A few short years after their formation, the pair climbed the ranks to reggaeton stardom, arriving in 2006 as one of the genre's most important groups. Both originating from Gurabo, Puerto Rico, the pair got their start performing at local house parties and clubs, Ken-Y singing and Rakim providing the group's lyrics and rap flow. Notice by record producer Chencho led to their first recording contract, with Money Machine Records, a label owned by veteran Notty Play, whose label, though influential, lacked reach and means. Appearing on mixtapes and compilations, the duo caught the attention of reggaeton MC Nicky Jam and producer/label owner Raphy Pina of Pina Records. The label switch to Pina Records proved very important in the group's success, offering opportunities to work with artists like Don Omar, Nicky Jam, Polaco, and Lito. Their debut record, Masterpiece met great success and positive reviews.
