In attesa di farci ascoltare il nuovo album, previsto per Ottobre su Nuclear Blast, i Lamb Of God hanno diffuso un singolo formidabile:
Willie Adler afferma:
"Grayscale has just a smack you in the face, bit of hardcore feel to it. We had basically finished writing the record and I wrote this song thinking it won't necessarily be a Lamb song. I sent it to Josh Wilbur, our producer, to check out and he responded with 'Perfect, this is the last song we need for the record!'"
