Lyrically, however, Pass Out is annoyingly monochromatic. Disillusionment and loss are the themes, expressed in lines like "I'm in a daze caused by pain/A failing force that wants to change/Painting the white to gray." It's downright comical to hear Hunter growl such drivel. But poetic subtlety has never been this genre's forte, and Chimaira is all about the riff. And there are riffs aplenty here. The album's third track, "Severed," ends with Hunter bellowing the song's title over a throbbing half-time crunch groove, and the chorus of "Split" recalls old Alice in Chains, a surprising and persistent influence on the band. The keyboards are often arbitrary and overdone; the only time they seem right is on the final track, the oddly Nine Inch Nailsish "Jade." Ultimately, however, this is a small complaint; Pass Out is national-caliber thrash.
