The music of Isis is a suitable metaphor for their twelve-year career: patient, meticulous, fraught with tension and gradually building towards an apex of seismic proportions. Rare is the record that finds the individual players as compelling as the sum of their parts, and Isis has achieved just that. While the monolithic guitars of Aaron Turner and Michael Gallagher remain a primary fixture in the Isis soundscape, the dueling instrumentalists continue to develop and expand upon their interplay. Together they evoke the emotional range of Wagner: brooding, triumphant, vengeful, and morose.
