[3] Luny Tunes was reggaeton's first major hitmaking production team, cranking out an assembly line of hit singles, club anthems, and CD mixtapes, all the while collaborating with many of the style's top vocalists.

[4][5] Luny Tunes were given their big break by DJ Nelson, a reggaeton pioneer who recognized their production talents, which had been well showcased on Héctor & Tito's A La Reconquista (2002), and signed them to his Flow Music label.

[2] Luny Tunes in turn made their major-label debut, alongside another promising young production talent, Noriega, on Mas Flow (2003).

The various artists album consisted of 100% original material featured most of reggaeton's top vocalists of the time (Daddy Yankee, Don Omar, Tego Calderón, Wisin & Yandel, Héctor & Tito, Zion & Lennox, Baby Ranks, Nicky Jam, Trebol Clan, and many more) and firmly established the duo as a go-to production team.

The following year Luny Tunes continued to further their reputation, establishing themselves as hitmakers when "Gasolina," one of their numerous productions featured on Daddy Yankee's Barrio Fino (2004), became a worldwide hit and club anthem.

In addition to Barrio Fino, Luny Tunes also contributed productions to acclaimed albums by Don Omar (The Last Don, 2003) and Tego Calderón (El Abayarde, 2003), as well as albums by Eddie Dee (Los 12 Discípulos, 2004), Ivy Queen (Diva, 2004), Zion & Lennox (Motivando a la Yal, 2004), Nicky Jam (Vida Escante, 2004), and Trebol Clan (Los Bacatranes, 2004) — all of this within a two-year span.

The album remains the most successful compilation in the history of the genre spawning world renowned hits such as: "Rakata" by Wisin y Yandel, "Mayor Que Yo" featuring Wisin y Yandel, Daddy Yankee, Don Omar, Tonny Tun Tun and Héctor el Father, "Mirame" by Daddy Yankee feat.

After their signing, the duo released their full-length debut album titled Luny Tunes Presents: Erre XI which spawned the single "Carita Bonita" featuring Pee Wee of Kumbia All Starz.
