Chingon

Chingón (Mexican slang for badass) is a Mexican rock band started by director Robert Rodríguez to record songs for his 2003 film Once Upon a Time in Mexico. The band features members of the Latin Rock band Del Castillo, which has released three albums. Chingon contributed on Mexico and Mariachis, a compilation album to Rodríguez' Mariachi Trilogy, and released their debut album, Mexican Spaghetti Western, in 2004.

Chingón also contributed their song "Malagueña Salerosa" to Quentin Tarantino's Kill Bill Vol. 2 – which Rodríguez scored – and a live performance by the band was included on the film's DVD release. They will also contribute to the soundtrack for his next film, a collaboration with Tarantino called Grind House.

Rodríguez plays guitar in the band.
