The best and most original band in the world. This band does not fall under any category of music. They are their own stuff. The music they make is so fucking crazy it makes you want to jiz your pants. After the break up of the band At the Drive-in, mars volta was born. And what a wonderful thing that was.
-Hey bud, whats that stain on your pants?
