Puerto Rican reggaeton duo Jowell & Randy spent years establishing themselves individually before joining together and rising to fame within a few years' time. Jowell (born Joel A. Muñoz Martinez in Springfield, MA, in 1982) and Randy (Randy A. Ortiz Acevedo; San Juan, Puerto Rico; 1983) each became involved with the burgeoning reggaeton scene during the late '90s. It was only once they joined forces as a duo with Zion & Lennox -- with Jowell supplying the raps and Randy the melodies, they truly began breaking into the recording industry. However, in particular, Jowell & Randy were a constant feature on Boy Wonder's series of popular Chosen Few compilations: Chosen Few: El Documental ("No Queiro Guillaera," 2004), El Draft 2005: La Nueva Generación del Reggaeton ("Siguelo Bailando Solita," 2005), and Chosen Few: El Documental, Vol. 2 ("No Voy a Parar," 2006). The duo's profile was increased significantly by Randy's guest features, especially De la Ghetto's "Sensacion del Bloque" (2006) and Tito el Bambino's "Siente el Boom" (2007), both of which were hits. In 2007 Jowell & Randy debuted as part of the group Casa de Leones, racking up a big hit with "No Te Veo." The song reached the #3 position of Billboard Latino, where it remained on the list for over 35 weeks. In 2007, the duo teamed up with fellow music artists Guelo Star and J-King & Maximan to form the group "Casa de Leones." December of 2007, the newly-formed group released the album "Los Mas Sueltos de Reggaeton", which allowed the artists to tour across the world including the United States, Mexico, Canada, Venezuela, Honduras, Colombia, Ecuador, Peru, Chile, the Dominican Republic, Europe, Italy, Spain, Switzerland, France, Germany, Holland, and the Canary islands.
In 2009, Jowell & Randy signed a contract with WY Records, led by reggaeton stars Wisin & Yandel. On May 4, 2010, the duo released "El Momento", their first album under the WY record label.
