This song was released as the lead single from Octahedron in Europe, whilst in the North America "Since We've Been wrong" was selected as the first release.
The song incorporates several different time signatures: 11/8, 9/4 and the common 4/4.
Frequent Mars Volta collaborator John Frusciante of the Red Hot Chili Peppers played the wah-wah guitar solo on this track. Mars Volta songwriter Omar Rodriguez-Lopez told DIY magazine why he likes working with the guitarist: "He's another musician I can utilise in my songs, in that he learns very quickly. When he plays for me, it's more like a musician executing a part. It's not collaboration in the sense that he's writing anything, but he's learning my parts in a matter of minutes and performing them in a matter of minutes."
The song's title refers to the name of a volcano in Ecuador.
