The Mars Volta returns with a fresh dose of epic rock"n"roll on its third studio album, "Amputechture." The eight-track set opens with the seven-minute "Vicarious Atonement," the closest the group has ever come to a ballad.The album then moves back to familiar expansive musical territory on the nearly 17-minute "Tetragrammaton," and also features two other tracks that clock in past the 11-minute mark, "Meccamputechture" and "Day of the Baphomets." The disc itself runs more than 76 minutes in length.In addition to contributions from Red Hot Chili Peppers guitarist John Frusciante, "Amputechture" also features Paul Hinojos" first studio work with the Mars Volta since joining as a touring musician in 2005. Hinojos previously played with Mars Volta principals Cedric Bixler-Zavala and Omar Rodriguez-Lopez in At The Drive-In.
