After
graduation from college, he recorded his first album titled Bomba
de Tiempo that he sold door-to-door, showing the album to patrons
at small bars, and eventually selling 500 copies.
Fonseca
was searching for a record label when he found the Colombian musician
José Gaviria and helped him in an initial recording with Sonolux in United States in 1997. The project stayed up in the air until 2002 when he signed with Líderes Entertainment Group, a label of EMI Capitol to produce his three upcoming albums.
Fonseca's self-titled debut album was released in February 2002 in Colombia and on December 26, 2005 internationally.The
album had a moderate success in his native country. The album spawned
four singles, "Mangangué", "Noche de Carnaval", "Sueño" and
"Confiésame". The album is highly influenced by the Colombian "tropipop" sound associated with Carlos Vives' albums. The album gained him considerable attention in Colombia, including the notice of artists like Shakira and Juanes, both of whom offered him subsequent collaboration and performance opportunities. Sharing the stage with Shakira on her Tour of the Mongoose and Juanes at Estadio El campín in Bogota garnered Fonseca the recognition and momentum he would need for his second album.
His second studio album, Corazón produced by Fonseca himself, Bernardo Ossa and the executive producer Alvaro Rizo, was released in May 23, 2006. Allmusic gave
the album a rating of three out of five stars. The album has reached a
peak position of number seven on the U.S. Tropical Albums chart. Three
of the album's eleven tracks became singles, including "Te Mando
Flores", "Como Me Mira" and "Hace Tiempo". The first song won Fonseca
one Latin Grammy and reaching the top 40 on the U.S. Latin chart.
