Plan B is a Puerto Rican Reggaeton duo, consisting of Chencho (real name Orlando Javier Valle Vega) and Maldy (Edwin Vázquez Vega), who are co-working cousins. At an early age they had an attraction to Reggaeton music; all their efforts finally began to pay off when they met the famous music producer, DJ Blass, who gave them two the opportunity to participate in a Reggaeton compilation album called Aliados Al Escuadron and released their first recording "Voy Subiendo" in 1999.
At the time they were called "The Panic" until after their song "Plan B" from the album Reggaeton Sex Vol. 2 (2000), also produced by DJ Blass.They further continued their careers in the genre by participating in compilation and live albums from DJ Blass like Triple Sexxx (2001), Reggaeton Sex Live (2001), Sandunguero Vol. 1 (2001), and eventually Reggaeton Sex Crew (2002).
