R.K.M & Ken-Y is a Puerto Rican reggaeton duo formed in 2003 by José Nieves (R.K.M) and Kenny Vázquez (Ken-Y). The artists are renowned in the Latin music world for being the first to successfully fuse mainstream pop music with the reggaeton street rhythms of Puerto Rico and expose the style to a wide international audience. The sound introduced by R.K.M & Ken-Y would go on to inspire the pop reggaeton songs of successful acts such as CNCO, J Balvin, and Maluma. The duo had a very successful career with the Spanish-speaking audience of Latin America, the United States, and Spain until their separation in 2013. In June 2017, the duo announced their official return by Pina Records. In mid-2021 the Duo confirmed that they are on hiatus and are currently working on their solo projects.
