The band has taken the sound-chassis of bands like AIC, Tool, Deftones, Metallica, Soundgarden and countless others, put balls under the hood and gave it more sophisticated engineering. A hard but steady drum beat paralleled by a determined, sometimes punishing bass line—solid hard ass rock/metal—fraught with balanced guitar riffs and the Walker vocal array that ranges from a deep, hard bass on the low end to an elevated scream on the upper. With hints of Cornell and Vedder in his voice, he draws it all from some deep, tortured place within.
