Jumbo is a rock band formed in Monterrey, México. They’re part of the “Avanzada Regia”, wich is a musical movement from the mid 90’s consisting of several rock and other genre bands, all of them originated in the same city.

Jumbo was founded in May 1997 with a 5 people lineup:

Alejandro Clemente Castillo aka “Castillo” in charge of vocals and lead guitar, Jorge Tamez Chapa “Flipi” on guitar, Carlos Alfredo Castro “Charly Pornet” on bass, Eduardo David González “Eddie on keyboard and Eduardo’s brother Enrique Demian Gonzalez "Bugs” manning the drums.

Before being “Jumbo” the band consisted only of Castillo, Charlie and Eddie, along with previous memebers Javier Othon and Rene Garza; and was called “Blueswagen” being mainly a cover band who played in bars and clubs.

Over time “Blueswagen” gained popularity until they signed with BMG.

Joined in ‘96 by Flip and Bugs the next year, they changed their name to their current name. This after a news report of the “worlds biggest baby” a baby boy who weighed over 100lb, nicknamed “Jumbo” Jin Li.
