Puerto Rican reggaeton duo Program B was formed by cousins Javier Valle Vega and Edwin Vázquez Vega, who pass the alter egos Chencho and Maldy, respectively. Originally known as the Panic, Program B began launching singles in 1998. Their full-length studio room debut, Un Mundo del Program B: Los Que La Montan, found its way to 2002, accompanied by several mixtapes and the state follow-up, Home of Pleasure, this year 2010. A set of 2013 singles — “Zapatito Roto” and “Chocolate” (the previous offering Tego Calderón) — peaked on top of the U.S. Latin graph, paving just how for 2014’s Like & Sex, which became their highest charting record. In past due 2016, the set released Planblive, their initial live album.
