From the very beginning, The Mars Volta was conceived as more than simply a new vehicle for Omar Rodriguez-Lopez and Cedric Bixler-Zavala. The group was to be a rebirth, a redrawing of their creative frontiers, a repudiation of the stylistic provincialism that had ultimately spelled the end of their previous band, At The Drive-In, a year earlier.

So, as The Mars Volta’s debut release, 2002’s Tremulant EP had much to accomplish within its three tracks and 19 minutes: to define the group’s ambitions and their possibilities, to sketch out a limitless horizon for their future adventures, and to shake loose the macho following they’d accrued with At The Drive-In’s final, breakthrough LP Relationship Of Command, the dudes in the moshpit who just wanted to slam-dance to post-hardcore riffs.
