Yeah, the guy from slipknot (Jordisen) is actually ...good, something very rarely found in Slipknot. The guy from Halford is Bob Jazombek, Ron Jazombeks little bro. I don't know much about him, but Ron is one of the most underrated shredders in the 80's. He wasn't as big as MacAlpine, Moore, Trafolla,Becker ect... This is because he actually did something different to them. It wasn't neo-classical shrapnell shred, so he didn't get the recognition. He was in the most technical band out there (until Spiral Architect came) "Watchtower"
