Randy Blythe posted a video today through his twitter account of him practicing with Cannabis Corpse for their upcoming show this January. Cannabis Corpse lost their singer and one guitarist in December and Blythe stepped up to the plate as a temporary fill-in. He can definitely pull off the growls although the quality is pretty low. We'll just blame that on the mic with an on-switch. He should pick this up as a full-time side project (oxymoron).
