Returning to Miami led to an increase in the dancehall flavor of his music. This, combined with Calderón's outspoken viewpoint that salsa had become too corporate and too safe, made 2004's El Enemy de los Guasíbiri a punchier, more hectic, more street-level affair. With the reggaeton genre blowing up with New York City's hip-hop tastemakers and spreading its influence further and further, Calderón soon found himself fielding offers from hip-hop producers while landing tracks on numerous street-level mixtapes. His voice ended up on remixes of Usher
's "Yeah," Fat Joe
's "Lean Back," and N.O.R.E.
's "Oye Mi Canto." Looking to expand beyond reggaeton, Calderón declared his 2006 release The Underdog/El Subestimado "a musical journey through the Afro-Caribbean culture." The album kicked off his relationship with the Warner Brothers imprint Atlantic. ~ David Jeffries, Rovi
