Chingon

Chingon is a Mexican rock band based in Austin, Texas and started by director Robert RodrÃ­guez to record songs for his 2003 film Once Upon a Time in Mexico.  They contributed on Mexico and Mariachis, a compilation album to RodrÃ­guez' "Mariachi Trilogy", and released their debut album, Mexican Spaghetti Western, in 2004. 

Chingon also contributed the song "MalagueÃ±a Salerosa" to Quentin Tarantino's Kill Bill Vol.  2 - which RodrÃ­guez 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.
