Lito y Polaco were discovered in the early 1990s by Spanish Hip Hop and Reggaeton pioneer DJ Eric Industry. They formed part of the hip hop/reggaeton group "La Industria" alongside MC Ceja, Jackie, TNT, Prieto Valdez and others. In 1998 Lito y Polaco became increasingly frustrated with their lack of pay and focus from DJ Eric being part of La Industria, thus they decided to leave and form their famous duo, eventually signing with Pina Recordsin 1999. There was much hype surrounding Lito y Polaco's signing with the Pina Records record label especially because of the company's top star Don Chezina bringing a high-profile to the imprint. Immediately, the duo made a huge impact in the underground scene of Spanish Hip Hop and Reggaeton with hit singles such as "Jenga Jenga", "In The Deadline", "Sucesos", "Maniatica Sexual" and "Mundo Frio". Their albums from the year 2000-2004 under Pina Records all went double platinum in Puerto Rico including "Masacrando Mc's", "Mundo Frio" and "Fuera De Serie" ; the last album being distributed by Universal Latino and the most successful product from the legendary duo internationally. In 2005, the duo separate amicably in order to pursue ambitions as solo artists. Lito MC Cassidy remained under Pina Records and collaborating with fellow artists RKM y Ken-Y and Nicky Jam. Lito never released a solo album under Pina Records and left in 2007 after a financial dispute. He continued to release mixtapes under his own imprint "La Republica" until present time. Polaco signed with Hector El Father's record label 'Gold Star Music' in 2005 and achieved moderate success during this time touring worldwide with Hector and being featured on high-profile records and albums such as "Sonando" featuring Freeway, "Mas Flow 2", "Gold Star Presents: La Familia" and "Los Rompediscotecas". Once Hector "El Father" left the music industry to pursue his faith in Jesus Christ, Polaco became an independent artist and remains one to present time. In 2013 Polaco released a mixtape "Back To The Underground: Polakan Edition" under the record label White Lion. The duo have recently reunited in 2015 and announced a new album accompanied by an international tour.
