With over five million albums sold throughout the world, they were at one time the top selling act in Colombia, and were placed on other charts including those of Japan, Switzerland, United States, and Chile.

Having similar music styles and influences in common, they hit it off very well, eventually teaming up and forming their production company, WinDose International.

The first single on "World Party" was the Latin Urban club hit "El Trago", produced by the dance music DJ duo of Victor and Danny Vargas (No relation to Rafael) The sound and popularity from "World Party" was the motivation that both Vargas and Rosa needed to build on a new sound in the ever changing Dance music circuit.

With the addition of Jose "Pickles" Fuentes, their friend and local club promoter and DJ from Vargas' neighborhood, they went on to form the 740 Boyz.

740 Boyz was the precursor to what defined the legacy of Fulanito, where Vargas first utilized his signature high-pitched chanted choruses and rap style.

With the growing success of many young urban Latin groups such as Proyect Uno, Ilegales and Sandy y Papo surging in South America, Vargas and Rosa were eager to tap in.

Vargas was well aware of the rising success of the grassroots traditional merengue genre known as Perico Ripiao (Spanish for "shredded parrot").

They merged their hip hop styles with the sounds of merengue, as well as samba and cumbia, and released "El Hombre Mas Famoso De La Tierra" in 1997.

[3] Fulanito's second studio album, "El Padrino" (Cutting, 1999) used many of the same elements that garnered them international fame, with only minor changes to the sound and the frontline.

The album received a Grammy nomination in 1999, and had several songs featured in John Singelton's modern day film release of Shaft.

With its hit single "Callate", hip-hop tracks "Otra Vez" and "Eight Million Ways", the sound that Fulanito producing was making waves for a change, while still staying grounded in its merengue roots with "Pecho A Pechuga", "La Tiembladera" and "El Generalissimo", a song that created slight controversy in the Dominican Republic.

Other artists and producers were invited to participate in the construction of the album to insure variety, depth and a breath of fresh air for Latin hip hop listeners everywhere.

The duo produced a salsa hip-hop track titled "Pa Que Sepa", properly utilizing a piece of the Roberto Ruena composition "Que Se Sepa", and also the track "Mataron El Negro", cleverly embodying a portion of the composition "El Negron Bembon", performed by legendary salsero Ismael Rivera.
