El nervio del volcán

El nervio del volcán is the fourth and final album by Mexican rock band Caifanes, released in the summer of 1994.

With bassist Sabo Romo and keyboardist Diego Herrera out of the band since the previous year, Saúl Hernández (vocals), Alfonso André (drums), and Alejandro Marcóvich (guitars) were the remaining band members left to record Caifanes' fourth studio album in Los Angeles, California between February and April 1994. The album included the hit singles "Afuera" and "Aquí no es así".

A tour began throughout Mexico, United States, Central America, Colombia, Chile, and Argentina, ultimately ending with the band dissolving on August 18, 1995 on their final show in San Luis Potosí, Mexico. Hernández later formed a new incarnation of his previous band, Jaguares, due to legal disputes and fallout with lead guitar Alejandro Marcóvich.

Guest artists included Graham Nash, Stuart Hamm, Federico Fong, Yann Zaragoza and Cecilia Toussaint.
