The success of Pa'l Mundo (2005) elevated Wisin & Yandel to the top bracket of reggaeton performers, especially in terms of hitmaking, and in the wake of this success, the two vocalists used their clout to launch their own sublabel, WY Records, and present an affiliate group, Los Vaqueros. Comprised of Tony Dize, Franco "El Gorila," Gadiel, and El Tío, in addition to Wisin and Yandel, the group made its debut on Los Vaqueros (2006). A year later Machete Music released a sequel, Los Vaqueros, Vol. 2: Wild Wild Mixes, which included nine new songs and five remixes, in addition to reprised material from the original album. A membership change to Los Vaqueros was apparently made between releases, with newcomer Jayko taking the place of El Tío, who wasn't credited anywhere on Wild Wild Mixes. ~ Jason Birchmeier, Rovi
